REDES SOCIALES

Social Networks.

LESLEY MILROY.

An individual's  social  network is  straightforwardly the aggregate of relationships  contracted with
others, and social  network analysis examines the differing  structures and properties of these
relationships. Such analysis has  been applied by variationists  fairly extensively over the last two
decades  or  so to explicate informal  social mechanisms  supporting language varieties  specific to
particular social groups. Researchers have also addressed the question of how some social groups
maintain nonstandard dialects  or minority languages, often over centuries, despite pressures (of the
kind described by Li ppi-Green 1 997) to adopt publicly legit imized natio nal languages  or  varieties .
Social network is better treated as a means of capturing the dynamics underlying  speakers'
interactional behaviors  than as  a f ixed  social cat ego ry (see Ec kert  2000: 1 - 3 3  for a discus s ion of
dif ferent  conce pt s  of "speaker variables" in  sociolingui st ic s) . Given that the ties  contracted by
individuals within and between  speech communities  may change for  many reasons, analysis  of change
in the operation of the same  social  network mechanisms which support localized linguistic  codes can
illu minate the pheno meno n of lingu is tic  change . Networ k-oriented accou nt s of linguis ti c change have
emerged bot h in variat ionis t  s tudies of cont em porary s peech comm unities, and as po st hoc
sociohist ori cal s tudies  of changes  com plet ed at earlier st ages  of t he language (Li p pi-Green 1 9 8 9,
Milroy 1 992 , Milroy and Milroy 1 9 85 , Nevalai nen 2 000) .

1 The Concept of Social Network
Social network analysis of the kind generally adopted by variationists was developed by social
anthropologis t s  mainly du ring t he 1 960s  and 1 970s (see Milroy 1 987a, Li  1 996 , Johnson 1 994) .
Contrary t o the as sertions of Mu rray (1 993 : 1 6 2) , it is clear from even a cursory reading of  the
literature that no canonical "real" procedure for analyzing  social  networks can be identified; scholars
from many different disciplines employ the concept for a range of theoretical and practical reasons.
For exam ple , Johnson's (1 994) survey alludes t o a wide range of approaches within anthropology
which hardly overlap with the largely quantitative modes of analysis described by Cochran et al.
(1990). This international and interdisciplinary team of scholars is interested in the role of networks in
providing  support  for urban families. Accordingly, their methods are to a great extent driven by a
concern with  social policy and practice.
Personal social networks are always seen as contextualized within a macro-level social framework,
which is "bracketed off" for purely methodological reasons-i.e. to focus on less abstract modes of
analysis capable of accounting more immediately for the variable behavior of individuals. Since no one
claims that personal network structure is independent of broader social, economic, or political
frameworks constraining individual behavior, a social network analysis of language variation does not
compete with an analysis in terms of a macro-level concept such as social class.
A fundamental postulate of network analysis is that individuals create personal communities which
provide a meaningful framework for solving the problems of daily life (Mitchell 1986: 74). These 
personal communities are constituted by interpersonal ties of different types and  strengths, and
structural relationships  between links can vary. Particularly, the persons to whom ego is linked may
also be tied to each other to varying degrees-ego being the person who, for analytic reasons, forms
the "anchor" of the network. A further postulate with particular relevance to language maintenance or
change is that structural and content differences  between networks impinge critically on the way they
directly affect ego. Particularly, if a networ k consi st s chiefly of st rong t ies , and t hose t ies are
multiplex or many-s tranded , and if the networ k is also relatively dense-i .e . many of ego's ties are
linked to each other-then such a network has the capacity to support its members in both practical
and symbolic ways. More negatively, such a network type can impose unwanted and  stressful
constraints  on its members. Thus, we come to the basic point of using network analysis in variationist
research. Networks constituted chiefly of strong (dense and multiplex) ties  support localized linguistic
norms, resisting pressures  to adopt competing external  norms. By the  same token, if these ties
weaken conditions favorable to language change are produced. The idealized maximally dense and
multiplex networ k i s shown in figu re  2 2 . I  in cont ras t wit h a loose- knit , u ni plex type of networ k
shown in (figure  2 2 . 2) .
A social network may be  seen as a boundless web of ties which reaches out through a whole  society,
linking people to one another, however remotely. However, interest generally focuses on first-order
network ties, constituted by those persons with whom an individual directly interacts. Second-order
ties are those to whom the link is indirect, as  shown also in figure  2 2 . I . Within t he firs t order zone , it
is i mport ant for the reasons  noted above to distinguish between "strong" and "weak" ties of everyday
life-roughly ties which connect friends or kin as opposed to those which connect acquaintances. To
supplement the notions of multiplexity and density, Milardo distinguishes "exchange" from
"interactive" networ ks ( I 98 8: 26 - 36) . Exchange networ ks consi st  of persons such as kin and close
friends with whom ego not  only i nt eract s regularly, but also exchanges direct aid, advice, criticism,
and support. Interactive networks on the other hand consist of persons with whom ego interacts
frequently and perhaps over prolonged periods of time, but on whom he or she does  not rely for
material or symbolic resources. An example of an interactive tie would be that between a store owner
and cu s tomer . In addi tion to exchange and int eractive ties , Li ( I 994) dis tinguishes a "pas sive" tie ,
which  seem s particularly i mport ant t o migrant or mobile individuals . Pas sive ties entail an absence of
regular contact, but are valued by ego as a source of influence and moral  support. Examples are
physically distant relatives or friends.
Eckert notes  that  the  people who comprise an individual's personal communities  change, as indeed do
the everyday problems which such personal communities help to solve (2000:  34). Furthermore,
individuals engage on a daily basis in a variety of endeavors in multiple personal communities.  Eckert
em ploys  the co nce pt of community of practice, whi ch is  closely relat ed to that  of social  network, to
locate the int eract tonal  s ites where  social  meaning i s indexed by Ii nguis ti c ele ment s, and Ii nguis t ic
change and  social  meaning are co-constructed.  A community of practice may be defined as  an
aggregate of people coming together around a particular enterprise (Eckert  2000: 35), and in her
analysis  of the  social dynamics  of language change among Detroit adolescents, Eckert focuses on
intersecting clusters of individuals  engaged in such enter pri ses , (2 000:  1 71 -2 1 2) .  Such clu s ters
co ns tit ut e gendered  subgrou ps ins tant iating t he adolescent  s octal categories which part ici pant s
the m selves  cons t ruct. Networ k analys is t ypically does not  attend t o the identi fication of such clus t er s
or the enter prises u ndertaken by me m bers , but deals  primarily wit h the  s truct ur al and co ntent
pro perties  of t he ties which cons tit ut e egocentric  personal  networ ks .
While close-knit networks vary in their degree of approximation to the idealized representation shown
in figure 2 2 . 1 , networks of this type are the interactional  site where localized  styles and norms of all
kinds are constructed. Thus, for example, Eckert (2000:  210) comments that  for the  high  school
st udent s s he s tudied , t he cons truct ion of local  s t yles was "a fu nct ion of integration into local
networks and access to information. The importance of information is clear at the level of clothing
style." She goes on to note that "[c]ertain aspects of linguistic  style are also negotiated consciously. I
can recall explicit discussions in my own high school crowd of _cool' ways to say things, generally in
the form of imit ations of cool peo ple . . . . But in general , lingui st ic influence t akes  place wi thout explicit
co mment and all t he more requires direct access to  speakers. The adoption of a way of speaking, like
a way of dressing, no doubt  requires  both access and entitlement to adopt the  style of a particular
group" (Eckert 2000: 211). Eckert is here describing very general  social mechanisms  by which local
conventions and norms-of dress, religion, and general behavior, for example-are negotiated and
created, and linguistic norms are no exception. Close-knit networks of the kind where this activity
takes  place are commonly contracted in adolescence. These are the linguistically influential peer
groups which are of such interest to sociolinguists attempting to understand the kinds of language
change as sociated wit h different point s i n the life  s pan (see Ker swill  1 996) . However, such networks
al so flou rish i n low-s tatu s co mmu ni ties (both ru rat and urban) in t he absence of social and
geographical mobility and are important in fostering the  solidarity ethos associated with the long-
term su rvival of socially di sfavored languages and dialect s .

2 Social Networks and Language Variation: Methods and Findings.
This  sect ion reviews  so me variation! st  st udies which have employed t he networ k conce pt , and begins
by noti ng that the effect of interpersonal relationships on language choices has been explored for a
long ti me in sociolinguis tics ; wit nes s Gauchat's (1 905) account of variation in the vernacular of the 
tiny Swiss village of Charmey. Much later, Labov's (1972) sociometric analysis  of the relationship
between language use and the individual's  position in the group resembles in important respects
Eckert's account of communities  of practice as the  sites where linguistic norms and social  meaning
are co-const ruct ed (see also Cheshire  1 9 82 for a co m parable accou nt of language variatio n in
adolescent peer groups) .  Follow! ng an ethnographic , non-quantit at ive tradit ion of research which has
st rongly i nfluenced variation! st methods , Gu mperz's  Discourse Strategies (1 9 82) provides an
extensive discus sion of t he effect s  of changing networ k s tructu res on language choice in bilingual
co mmu nities . Chambers (1 995) identif ies a s tudy carried out i n Belfast , Northern Ireland , i n the mid-
1 9705 (Mitroy and Mitroy 1 978 , Mitroy 1 987a) as the firs t sys tematic accou nt of the relatio nshi p
between language variation and social  network structure in the variationist literature. In this  section, I
discuss  some of the major methods and findings  of this research, before reviewing three later studies
which take it as a point of departure.
An ethnographically-oriented dat a-collect ion procedu re , influenced by the wor k of John Gum perz
ment toned above , was  used i n Belfast whereby t he researcher introduced herself to initial contacts as
a "friend of a friend"-i.e. a second order network contact of the people participating in the  study.
These i nit ial cont act s pas sed her  on t o ot hers , and observatio n and recording co nti nued u nt il
sufficient s peakers wit h the des ired characteris tic s (e . g.  of age and gender) were  sampled. Crucially,
the unit  of study was the pre-existing  social group, rather than a series  of isolated individuals as
representatives  of particular social categories.  By attaching herself to this group and retreating to its
fringes as interactions between members  progressed, she was able to obtain large amounts  of
spontaneous  speech as well  as  relevant social and demographic information, and the effect  of the
observer  on the data was lessened.  Fieldwork procedures  of this general type have been used
extensively in both bilingual and monolingual communities (as described by Mitroy et al.  1 995) , and
problems  of access are rarely re ported . Ker swill (1 994) describes  their im plementat ion in wes t ern
Norway.
Data recorded in the Belfast study were examined to compare the language patterns of 46  speakers
from three low status urban working-class communities-Ballymacarrett, Hammer, and Clonard. Eight
phonological variables, all  of which were clearly indexical of the Belfast urban speech community,
were analyzed in relation to the network structure of individual  speakers. In all three communities
networks were relatively dense, multiplex, and often kin-based, corresponding to those described by
many investigators as characteristic of traditional, long-established communities minimally impacted
by social or geographical mobili ty (see , e . g . , You ng and Wilmott 1 96 2, Cohen 1 982) .
Although a social class index of the kind used in the early days of socio-linguistics could not
discriminate between these speakers, the extent of individuals' use of vernacular variants was found
to be strongly influenced by level of integration into neighborhood networks. For example, some
people worked outside the neighborhood and had no local  kin and few local ties of friendship, while
others were locally linked in all these capacities. Such differences in personal  network structure clearly
spring from many complex social and psychological factors, and so interact with a number of other
variables; examples are generation cohort , t he recent his t ory of the neighborhood, and gender. Since
the gender / networ k relationshi p has  proved to be suggestive of a general explanation of gendered
patterns of language variation and change, I shall comment on it here.
Men in the Belfast neighborhoods generally contracted denser and more multiplex localized network
ties than women, and network structure correlated with language use patterns differently for men and
women. A similar disjunction between the effect  of male and female networks is reported in Dubois
and Horvath's (1998) variationist account of Cajun English. Eckert confirms and elaborates the
st rongly gendered character bot h of networ k clus ters and of t he networ k/ language relationshi p
(2000: 1 2 0- 4) . Noti ng a t endency for wo men t o contract ties acros s a wider social  s pectrum,
Chambers (1 995: 1 2 4-8) attributes the frequently observed tendency of men to approximate more
closely than women to vernacular norms to this difference in network structure. In broader
investigations of the  social trajectory of language change in two different urban locations, Mitroy and
Mitroy (1 99 3) and Docher ty et al. (1 997) ex plore the interaction between gender and network; male
nor ms are as sociated wit h localized variant s, and female norm s with  su pra-local (bu t not neces sarily
st andardized) variant s. Mi troy (1 999) attributes the relative conservative , localized charact er of male
speech behavior to the particularly constraining effect of male peer networks. The interacting effect of
network and gender on patterns of language variation and change remains an extremely important research topic which will be alluded to again in this chapter.
2.1 Measuring social network structure.
Given the ethnographic orientation of  social  network analysis, a major challenge for variationist
researchers is to devise a procedure for characterizing differences in network structure which reflects
the everyday social  practices of speakers. The Belfast study developed a Network Strength Scale to
as sess  s peakers' networ k characteris tics on five indicat ors of mutt i plexity and density. Mitroy (1 98 7a:
1 41 f) describes in det ail both the rationale for  selecting the indicators and procedures for
operationalizing the Network Strength Scale.  Briefly, a score of one or zero was assigned to each
indicator, and a total  network strength score calculated for each individual which was  the  sum of
individual indicator scores. The indicators focused on various  relationships  within the nelhborhood
of kin, work, and friendship which had emerged in the course of the fieldwork as significant to
participants. They were

·membership of a high density, territorially based group (e.g. a bingo or card-playing group,
a gang, or a football team or football supporters' club);
·having kinship ties with more than two households in the neighborhood;
·same workplace as at least two others from the neighborhood;
·same workplace as at least two others of the same gender from the neighborhood;
·voluntary association with workmates in leisure hours.
A series of statistical analyses revealed a clear relationship between personal network structure and
phonological variation, usually complicated by the interaction of other social variables such as the age
and gender of the speaker. The strongest vernacular speakers were generally those whose
neig hbor hood networ k ties were the st ronges t . Figu re 2 2 .3 illu st rates this t endency in Baily macar rett, where patterns of use for the variable (th) are plotted against network structure. The variable pattern
represented here is the presence vs. absence of the voiced interdental fricative  [6] in intervocalic
contexts in such words as  
mother and brother; deletion scores for each speaker, whose age group
and gender are also specified, are plotted as percentages against individual network strength scores.
The interacting effects of gender and network noted above are also evident; not only are women's
network scores lower than men's, but the woman with the highest (th) index scores a full  10 percent
lower than the man who scores the lowest.
It is on the basis of language/network relationships  such as these across several linguistic variables
and many more  speakers that the close-knit network is interpreted as an important mechanism of
dialect maintenance.
2.2 Network concept in small-scale communities: some examples.
The attractions for variationis t s of a networ k ap proach can be s tated quit e briefly. Fir st , it provides a
set of procedures for studying small groups where speakers are not discriminable in terms of any
kind of social class index-as for example the eastern US island communities investigated by Wolfram
et al. (1999). Other examples are minority ethnic groups, migrants, rural populations, or populations
in nonindustrialized societies.
A second advantage of a social network approach is that it is intrinsically a participant rather than an
analyst concept, and so has the  potential to elucidate the  social dynamics driving language variation
and change. Finally, network analysis  offers a procedure for dealing with variation between individual
speakers, rather than between groups  constructed with reference to predetermined  social categories.
Eckert (2000:  1-33) discusses in some detail the very different concepts  of a social variable implied
here . These methodolog ical i ssues are exem plified in many s tudies carried ou t in the 1 9 80s and
1 9905, such as t hat by Rus sell (1 982 ) in Mo mbasa, Kenya; Schm idt (1 9 85) of Aus tral ian Aboriginal
adolescent s ; Borto ni-Ricardo (1 9 8 5) of changes in t he language of r ural m ig rant s  to a Brazil ian city ; V.
Edwards (1 9 86) of t he language of Britt sh black adolescent s ; School ing (1 990) of language dif ferences
among Melanes ians in New Caledonia; Lip pi-Green (1 9 8 9) o n dynam ic s of change in t he ru ral alpine
vi Ilage of Gros sdorf, Aus tria; W. Edwards (1 992)  of variat ion in an African-Amer ican community in
inner-cit y Det roit ; and Maher (1 9 96) of t he  pers is tence of language differences in the isolated island
co mmu ni ty of St.  Bart hlemy, French Wes t Indies . Li ppi -Green (1 9 8 9), Edwards (1 992 ) and Borto ni-
Ricardo (1 9 8 5 ) are briefly reviewed below, to illustrate a range of different applications of the network
idea.
The relative  socioeconomic  homogeneity of the inner-city Detroit neighborhood studied by Walter
Edwards (1992) made social  network analysis an attractive procedure for dealing with intra-
community linguistic variation. While the principal factor associated with choice of variant was age,
the most important  factor which distinguished age-peers  of a comparable  social and educational
background was  participation in neighborhood culture. Edwards interpreted  such participation as
indicative of relative integration into local networks, and measured this integration by means of a
Vernacu lar Cu Itu re Index . Thi s was const ruct ed from res ponses to  1 0 s tat ement s which could range
from Strongly Disagree (1  point) to Strongly Agree (4 points). Five  statements were designed as
indicators of the individual's  physical integration into the neighborhood, and, like the Network
Strength Scale u sed i n Belfast , focused on localized int eract ions with ki n, wor kmates , and f fiends (e . g.
"Most  of my relatives  live in this neighborhood or with me"; "Most  of my friends  live in this
neighborhood"). Convinced of  the importance of attitude in accounting for variation, Edwards
designed the other five  statements to indicate evaluations of the neighborhood and of black/white
friendship ties (e.g. "I would like to remain living in this  neighborhood"; "I do not  have white friends
with whom I interact frequently").
Yet another set of indicator s was relevant to Li ppi-Green's (1 989) s t udy of language change in
progress in Grossdorf, an isolated Austrian Alpine village with 800 inhabitants. Noting the
unhelpfulnes s of macro-level conce pt s such as clas s in u ncovering the relationshi p between language
variation and social structure, Lippi-Green examined in considerable detail the personal network
structures of individuals, constructing a scale which used 16 differentially weighted indicators. Some
of these were associated with the familiar domains of work, kin, and friendship, while others dealt
more  s pecifically wit h local condit ions-such as the nu mber of grand parent s familiar t o the  speaker
who was a core member of the village, or the involvement of the  speaker's employment with the 
tourism industry. Particularly important were indicators which linked  speakers to major village family
networks. Overall, the best correlate of linguistic behavior (conservative vs.  innovatory) was
integration into three important networks, including those which involved workplace and exposure to
non-local language varieties. However, the  subtlety of Lippi-Green's network measurement scale
allowed her to examine correlations  both with all of it and  some part s of it , revealing for example
gender- s pecific social t raject ories  of language change and variation.
In addressing the changing language behavior of mobile individuals , Bo rtoni-Ricardo's (1 9 85) accou nt
of the  sociolinguis t ic adjus t ment of rur al  mig rant s t o Br azlandia, a satellite cit y of Brasilia exem plifies
a very different ap plication of the networ k conce pt fro m those di scu s sed above . Again , the  social
clas s  conce pt is not particularly u seful  i n this cont ext, since it does not discriminate between the
individuals studied by Bortoni-Ricardo, all of whom were relatively poor. Taking the group's own
linguistic norms  as a starting  point, Bortoni-Ricardo examined the extent to which speakers  had
moved away from thei r st ig matized Cal pi ra dialect , rat her than att em pting t o ident ify a linguis tic
st andard "target"
Bortoni-Ricardo's main hypothesis is that the change in social structure associated with rural to urban
migration involves a move from an "insulated" network consisting largely of kinsfolk and neighbors to
an "integrated" urban network where links are less multiplex but contracted in a wider range of social
co nt ext s . The linguis tic count er part of t his change is increasi ng dialect dif fuse-Mes s-a movement
away f rom t he relat ively focu sed norm s of the Cal pi ra dialect ( see fu rther Le Page and Tabouret - Keller
1 9 8 5) . Two se parate networ k i ndices are cons tructed to measu re the changing patterns of the
mig rant s' s ocial relat ionshi ps ; t he integration index and the urbanization index. The integration index
assesses relevant characteristics of the three persons with whom each migrant most frequently
interacts-for example, whether they are kin or non-kin, whether ties were contracted prior to
migration. The final score measures progress in the transition from an insulated to an integrated type
of network-effectively the gradual loosening of close-knit network ties. These changes are correlated
with a linguis tic movement away from t he norms of the Cal pi ra dialect .
The urbanization index focu ses not on the migrant , but the characteris t ic s of members of his or her
personal network, such as educational level and mobility; indicators are selected to assess the extent
to which the migrant's contacts are integrated into urban life. In developing these two quite different
types of index Bortoni-Ricardo extends the application of the network concept beyond an analysis of
small, close-knit groups of the kind described so far to consider the extent to which individuals have
detached themselves from such groups and the linguistic consequences of that detachment.
In an extended di scu ssion of sociolinguis t s' use of the networ k conce pt, Mu rray (1 993) is  particularly
cr itical of the quantit ative analysis employed by Labov (1 972) and Milroy (1 987a) on grounds which
are more controversial than he claims, and are moreover not always entirely clear.  Murray's  strongly
stated claims of what constitutes an appropriate approach to social network analysis and an
appropriate  statistical method are disputable.  Moreover, a subsequent clarification in American
Speech (Bu tter s 1 995 : 2 0) point s  out  that  s pecific crit icis ms  of Milroy's s tat is tical  procedures and
result s  res t on a mis reading of  her text.

3 Language Maintenance and Shift in Bilingual Communities.
Although the discus s ion so far has  concentrat ed on the language / networ k relationshi p in monolingual
co mmu nities , researchers  inves ti gati ng the  social mechanis ms  of language mai nt enance and  shift in
bilingual co mmu nities  have em ployed a variant of the  same general  principle: networks  constituted
chiefly of  strong ties function as a mechanism to  support minority languages, resisting  institutional
pressures to language  shift, but when these networks weaken, language  shift is likely to take place.
This  section reviews  some of this work, starting with a consideration of the network structure
characteristic of immigrant communities.
It has  sometimes been suggested that close-knit networks  such as those studied in Belfast and
Detroit are marginal to contemporary urban life; for example, there is a large sociological literature on
"the  stranger", the mobile, marginal individual who is often seen as typical of a modern city dweller
(Harman 1 988) . While this  perce ption cert ainly reflect s  important as pect s of contemporary urban life
(we  shall later discuss the linguistic consequences of social and geographical mobility) it does not tell
the whole story. Certainly traditional working-class communities like the Italian American "urban
villagers" described by Cans (1 96 2) or t he close- knit Yorkshire mini ng communities described by
Dennis et at. (1 95 7) have all but disappeared . However , Giddens (1 989) point s out that
neighbor hoods involving close kinship and personal  ties  seem still to be created rather than
discouraged by city life, since those who form part of urban ethnic communities gravitate to form ties
with, and often to live with, others from similar linguistic or ethnic backgrounds. Hence, the older
style of close-knit working class community is apparently being replaced in industrialized countries
by similar types of community created by newer immigrants. Dabne and Moore (1995) describe the
supportive function of such migrant networks during the period when immigrants are developing
resources to integrate more fully into urban life.
The type of close-knit network structure which seems to help maintain community languages is
therefore by no means a residue of an earlier type of social organization; not only immigrants, but
also long-term stigmatized and marginalized minorities, like the New York Puerto Ricans studied by
Zentella (1997), construct personal communities which function as  powerful  support systems in a
hostile environment . Gal (1 978) and Li (1 994) , whose work i s discus sed i n more det ail below, have
correlated observed patt ems of language u se with s pecific networ k patterns in much the same way as
researchers working in monolingual communities. Indeed, Gal explicitly compares her model of
language shift to a variationist model  of language change, in being both gradual and rooted in
synchronic patterns of variation in language use. Zentella also adopts a broad variationist perspective,
but like Gum perz (1 982) , u ses the conce pt of network informally and non-quantitatively.
Gumperz's (1 982) accou nt of the Slovenian / German bilingual co mmu ni ty in a remote part of Austria's
Gail Valley associates the move towards monolingualism with economic changes. Members of this
poor and socially stigmatized farming community had traditionally been embedded in classic close-
knit networks of mutual  support which linked them in many capacities-as co-workers, neighbors, and
friends who socialized together within the boundaries of their community. However, such behaviors
changed as the economy shifted from a dependence on subsistence farming to a primarily service
economy. Improvement s in the road sys tern gave rise to a host of other changes which affected
network structure and, ultimately, language behavior followed. Farmers  sold produce to incomers and
to factories  rather than dealing with other local  farmers; farm buildings were converted into tourist
accommodation for the many visitors entering the area; work and leisure activities were no longer
confined to the immediate locality. As many day to day interactions came to be with urban outsiders,
villagers lost their reliance on the local  support network. Although of course local conditions give rise
to variations, the pattern Gumperz describes here appears to be a very general one in much of
western Europe (and probably elsewhere in t he developed and develo ping world) . 0' Riagain_s (1 997)
description of a series of st udies car ried ou t in Ireland between 1 973 and 1 99 3  sugges t s a sit uation
broadly si milar t o that in t he Gail Valley where change to a service economy triggers associated
change in personal social  network structures. Consequent  changes in the categories of individual
involved in face-to-face encounters  shifted the balance from bilingual Irish-speaking insiders to
monolingual English-speaking outsiders, inevitably resulting in the further decline of Irish.
Gal's (1 978) analysis of language shift i n the bilingual German / Hu ngarian com mu nit y in Oberwart,
Aus tr ia, identif ies Sim ilar tr iggers . Individuals are measu red in t er ms of the relative " peasant nes s" (a
local  social cat egory) of t heir  networ ks . This variable o perat es dif ferent ly for men and wo men ( recall
thi s pattern in other networ k s tudies) bu t is fou nd to correlat e more closely t han individual  peasant
st at us wit h patterns of language choice . Like t he Gail Valley and the Irish Gaeltacht, Oberwart had
been bilingual for several centuries, and again, changes in network structure are associated with
higher -level economic changes . We now t urn to Li's (1 994) and Zentella's (1 997) wor k in i mmigrant
co mmu nities where t ypically pressu re to as similate to t he monolingual  nor m of t he hos t cou nt ry is
int ense and , i n contras t t o the co mmu nities discu s sed above , a pattern of language  shift over three
generat ions is co mmon. Grosjean (1 982) and Jorgensen (1 998) describe these pres su res in t he Unit ed
States and Euro pe res pectively.
Despite a general  sense that Spanish in the United States is resistant to shift (Bourhis and Marshall
1999) Zentella provides evidence of this  three-generational  shift pattern in a Puerto Rican community
in New York City (et b/oque). In an account which is  compiled from long-term participant oservation,
she  notes some characteristic sociolinguistic patterns. First, while choice of code is  heavily network-
dependent, several distinguishable varieties of both Spanish and English give rise to multiple-code repertoires (Zentella 1 997: 4 8) . For example, while you ngs ters and you ng mother s have access t o a
range of Spani sh and Engl ish codes , t hey favor a Puerto Rican variety of English. Older men and
women however prefer Puerto Rican Spanish, while "young dudes" favor African-American Vernacular
English but also have access to varieties of Spanish and English. Many of the children speak very little
Spanish, mixing Spanish into their English to produce the code popularly described as  Nuyorican;
interestingly, only one child in Zentella's  sample is monolingual in English. Patterns of code choice
from this multidimensional repertoire are thus systematically associated with a range of distinctive
gender- and age-related networks.
Zentella comments on the  significance of what she describes as "the Puerto Rico language learning
connection" in offering an explanation of the  strength and persistence of Spanish in New York City
and elsewhere in the United States. She cites the combined effect of continuing network ties of
immigrants to individuals  in adjacent Spanish-speaking countries of Latin America, and cyclic
patt ems of immi grat ion (see agai n Bourhis and Marshal I 1 999) . Thi s Puerto Rican connect ion (and it s
counter part in ot her S Danish- speaki ng co mmu nities  in t he United St ates) may explain why young
peo ple u se a mixed S Danish-Engl ish code; in accordance with the expected pattern of language  shift
in immigrant  communities, they have  shifted substantially to English mono-lingualism but still need
to communicate with Spanish monolingual speakers.
Li (1 994) and Milroy and Li (1 995) re port an i nvestigation of  social traject ories of language shift which
as sociates different network t ypes with variable patterns of language use. However, they describe a
much less complex community repertoire than Zentella, providing a quantitative analysis of both
network types and language patterns. Three migrant groups are distinguished, overlapping with (but
not exactly corres pondi ng to) a grand parent , parent, and child generation . Each grou p co ntract s
charact eristically di fferent types of networ k ties, t he fir st as sociating mainly with ki n, the second
chiefly with other British Chinese, and the third more extensively with non-Chinese peers. Variable
network patterns were in turn correlated with seven different patterns of language choice, where
English and Chinese were used either monolingually or in different combinations. Following Milardo
(1988), interactive and exchange networks were distinguished, corresponding roughly to "weak" and
"strong" types of tie.
Since the Chinese in Tyneside did not live within a specificable neighborhood, assessments of network
strength could not be based on the territorially restricted strong ties as in several of the studies
reviewed in the previous section. Instead comparative analysis of individual exchange networks was
based on a list of up to 20 persons who constituted significant and regular contacts for each
individual, adapting the procedure described by Mitchell (1986). These sets of 20 could then be
compared on relevant dimensions-for example, different ethnic compositions. Not surprisingly, the
strongest ethnic networks were associated both with the oldest generation and with the most
extensive use of Chinese, and the weakest with the 8ritish-born generation and with the most
extensive use of English. There were, however, many subtleties associated with different  network
patterns within each group; particularly interesting is the role of the TrueJesus Church, one of the
community's institutions.
Li (1 995) sugges t s t he raison d't re of this church to be a support mechanism for cultural and
socialization activities rather than a religious institution, noting that member families were distinctive
in having contracted pre-migration network ties on the island of Ap Chau, close to Hong Kong. He
further documents a very much stronger pattern of Chinese language maintenance amongst the
young Brit ish- born members of the True Jesu s Church t han among s t the you ng co mmunity as a
whole , a patt ern att ribut ed t o the  st rong t ies maint ai ned by True Jesu s young st ers with church
members monoli ngual in Cant onese . Interestingly, Li also notes a pattern of fluent Cant onese / English
code m ixing as character! st ic of the True Jesus teenagers , which he explains  in much the  same way as
Zentel la (1 997) explains wides Dread S panish/ Engli sh mix ing by New Yor k Cit y Puert o Rican
young st ers . In both cases the young people have come up with a similar  solution to a similar problem;
proficiency in the community language is  limited, but they maintain network ties which require them
to communicate with non-English speakers. Thus, a network analysis can help explain not only the
social trajectory of language shift, but specific patterns of code  switching (see also Labrie's (1988)
network-based account of code  switching by It al tans  in Montreal) 
4 Weak Ties and Theories of Language Change.
Social network analysis has most commonly been employed in communities where ties  between
speakers  are generally strong. While  studies such as those reviewed above  show that it is  relatively
straightforward to operationalize the network concept in this way, how to handle socially and
geographically mobile  speakers whose personal  network ties are not predominantly dense or
multiplex i s much les s  obviou s . I n fact, networ k- based accou nt s of such s peakers  are rare , and the
only st udy exami ned  so far which has  attempted anything like this  is Bortoni-Ricardo's (1985) account
of the progressive urbanization patterns of Brazilian rural migrants. Geographical and  social mobility
is, however, the rule rather  than the exception in contemporary cities, and an increasing amount of
work carried out by variationists within dialect contact frameworks focuses  on such  speakers (see for
exam ple Tr udgill 1 9 86, Trudg ill and Brit ai n forthcoming , Chambers  1 995:  5 2 -6 5 , Kerswill and
Will tarns  2000) . Chambers (1 992) po int s out t hat sociolingu is tic s  as well as dialectology is quite
generally oriented to non-mobile  speakers  in isolated communities; the focus of network  studies  over
two decades has  reflected this  orientation.
At a purely operational level, loose-knit networks are hard to work with. Analysis of close-knit
networks involves comparing  speakers who differ from each other in certain respects (for example,
multiplexity of ties contracted at the workplace) but are still  similar enough in other relevant ways for
a comparison to be meaningful. But it  is difficult to see how the loose-knit network structures of
individuals who differ from each other in many different  respects (educational level, occupation,
region of origin, mobility inter alia) might meaningfully be compared with each other. This problem
was noted in the Be|fas t suburbs of Andersonst own and Braniel (Milroy 1 98 7b:  I 0 8) and was
encou ntered also in an att empt to ap ply social networ k analyst s i n the prosperous Bert in subu rb of
Zehlendorf (Ditt mar and Schlobins ki 1 98 8) . However, from t he pers pective of a per son who has
changed em ployment and place of residence  several times, the networks of speakers studied in
Belfast, Detroit, and Grossdorf are all close-knit , and m ight be compared in a general way with those
of more mobile speakers (see Kerswill and Williams  1 999) .
To identify these operational  difficulties  is  not to suggest that loose-knit networks are uninteresting
to the variationist: quite the contrary. For if a close-knit network structure  supports localized
lingu is tic  norms and res is t s change ori ginating f rom out side the network, the corollary, that
communities composed of weak ties will be  susceptible to such change, is also likely to hold.
Follow! ng Granovetter's (1 973) argu ment that "weak" and ap parently i ns ig nif icant inter personal ties
(of "acquaintance" as op posed to "friend" , for example) are im portant channels through which
innovation and influence flow from one close-knit group to another Milroy and Milroy (1 985 ) have
pro posed t hat Ii nguis t ic i nnovators are  I ikely to be i ndividual s who are in a position to contract many
weak ties. Since  such weak ties link close-knit groups to each other and to the larger  regional or
national  speech community, they are likely to figure prominently in a socially accountable theory of
linguistic diffusion and change.
Milroy and Mitroy (1985) argue that a "weak tie" model of change can account rather generally for the
tendency of some languages to be more resistant to change than others (Icelandic vs. English, or
Sardinian vs. Sicilian, for example). They suggest that a type of social organization based on
overlapping close-knit networks will  inhibit change, while one characterized by mobility (for whatever
reason), with a concomitant weakening of close ties, will facilit at e  it. Grace (1 992 ) explains  in a s imilar
way so me puzzling development s among t he Au st rones ian languages , whi ch  show widely di ffering
patt ems of  su sce pti bility t o change inexplicable in t erms of tradit tonal assu m ptions (see also Grace
1 990) . As well as ex plat ning dif ferent large -scale Ii ngui st ic out comes  by co m paring different t ypes of
social  organizat ion , the weak tie model can account for  specific  problematic examples of change, of
which two are considered below.
Innovations have been widely observed to skip from city to city, bypassing intervening territory. This
appears to be the pattern of the Northern Cities Shift, a vigorous change in vowel systems affecting
cities of the northern USA from western New England to an unspecified point westward (Labov 1991,
Wolfram and Schilling-Estes 1 998: 1 3 8) . On the ot her side of t he At|ant ic, Trudgill (1 988) notes t he
relatively recent adoption by young speakers in Norwich of a merger between  / f /    / q/  and  / v/
  / 6/  (as in fin  thin," lava lather) . Milroy (1 996) subsequently documents thi s merger by young
working-class speaker s in the northern English cities of Sheffield and Derby, and Stuart-Smith (1999) reports its recent appearance yet further north in Glasgow. As it saliently indexes working-class
London speech, this change, in the British context, appears to be contact-induced rather than to
originate from within communities. While attributing its rapid spread to NonNich to greater mobility
and contact between speakers, Trudgill points out that the teenagers who use the merged variants are
less mobile than their seniors and tend to contract close ties locally. For this reason, it is hard to
explain the precise mechanisms of diffusion in terms of close contact between London and Norwich
speakers. The same objection can be made even more tellingly since this very vigorous change has
extended across large areas of urban Britain in the years since Trudgill's observations of its spread to
Norwich. A weak tie model would however predict its diffusion from one community to another
through multiple weak ties; in fact, Trudgill suggests tourists and football supporters as individuals
who might be implicated in the diffusion process (1986: 54).
A second problematic case of change to which a weak-tie model offers a principled solution involves
the alternating phonolexical variable (u), as in pull, pus/7, foot, discussed in detail by, for example,
Milroy (1987a) and Milroy (1992). A rounded and an unrounded vowel variant appear in a lexically
limited set, the unrounded variant strongly indexing working-class identity. Figure 22.4 provides clear evidence of cross-community consensus between young (but not middle-
aged) speakers on the use of these alternative realizations to index gender also in the three working-
class communities of Ballymacarrett, Hammer, and Clonard. However, the fact that middle-aged
Ballymacarrett speakers use (u) to index gender in much the same way as younger speakers in all
three communities suggests that the change is diffusing from Ballymacarrett. The problem is this:
how has this change crossed the notorious sectarian lines of demarcation in the Belfast of the 19705,
since the civil disturbances which began during the childhood years of these young speakers
prevented them from contracting close ties across the sectarian divide? Older speakers, who report
having contracted many cross-community ties prior to the civil disturbances, display no cross-
community consensus on the use of (u). The age-related pattern of this change is puzzling if we
adopt the commonsense assumption that innovations are transmitted via strong ties (for such a
model, see Labov 1980: 261; Labov and Harris 1986), but not if we assume that the conduits of
innovation are the multiple weak ties of everyday urban interaction in the neutral areas outside close-
knit community territories (for further discussion of this issue, see Milroy and Milroy 1985).
Although it may at first seem counter-intuitive, a “weak tie” model of change is plausible for several
reasons, as suggested by Granovetter (1973). First, persons central to a close-knit, norm-enforcing
group are likely to find innovation of any kind socially risky, but the adoption of an innovation already
on the fringes of the group less so. Second (in the networks of mobile individuals at least), weak ties are more numerous than strong ties, providing links to many more individuals; consider, for example,
the ties set up by participants at academic or business conferences, which link cohesive groups
associated with each institution and provide conduits for new ideas and information. Conversely,
information relayed through strong ties tends not to be innovatory, since strong tie contacts are likely
to be shared (that is to belong to overlapping networks). Thus, mobile individuals who have
contracted many weak ties, but occupy a position marginal to any given cohesive group, are in a
favorable position to diffuse innovation. Interestingly, this argument is consistent with the traditional
assumption of historians of language that the emergent, mobile merchant class were largely
responsible for the appearance of northern (and other) dialectal innovations in Early Modern London
English (see, for example, Baugh and Cable 1978: 194). Using standard variationist methods,
historical sociolinguists have begun to examine systematically the social trajectories of such earlier
changes with attention to the effects not only of social network, but of gender and social status, with
promising results (Nevalainen 1999, Nevalainen and Raumolin-Brunberg 1996, Tieken-Boon van
Ostade et al. in press). Sociohistorial linguistics continues to develop as a significant subfield of
variationist theory.

5 Social Network, Social Class and Mobility.

The weak tie model of change discussed above can illuminate the dynamics of dialect leveling-that is
the eradication of socially or locally marked variants (both within and between linguistic systems) in
conditions of social or geographical mobility and resultant dialect contact. Leveling might reasonably
be viewed as a linguistic reflex of the large-scale disruption endemic in the modern world of close-
knit, localized networks which have historically maintained highly systematic and complex sets of
socially structured linguistic norms. Such disruption arises from (for example) internal and
transnational migration, war, industrialization, and urbanization. While these dynamics have operated
earlier and more intensively in colonial contexts, as discussed by Chambers within a broad social
network framework (1995: 57-66), they continue to affect geographically or socially mobile
populations. In any event, leveling gives rise to homogenization and a tendency for the localized
norms of the kind supported by a close-knit network structure to become obliterated (Chambers
1995, Trudgill et al. 2000, Kerswill and Williams 2000, Britain 1997, Watt and Milroy 1999). This
process raises interesting psycholinguistic as well as sociolinguistic issues concerning the functions
of close-knit networks, which are briefly explored below.

On the basis of evidence from language attitudes research, sociolinguists generally assume an
ideological motivation to underlie the long-term maintenance of often stigmatized norms in the face
of pressures from numerically or socially more powerful speech communities; speakers want to sound
(for example) Welsh, Irish, Northern English, New Zealandish, Canadian, African-American, American
Southern and unlike whatever social group they perceive themselves as contrasting with. The dialect
loyalty of such speakers and their resistance to change originating from outside the group is usually
said to be motivated by their desire to index group identity. Yet, motivations alone are insufficient to
maintain nonstandard varieties reliably (see Wolfram et al. 1999 for a discussion of this issue in an
American context). Relevant here is Payne's (1980) demonstration of the social conditions needed for
children to learn the highly localized phonolexical complexities of the Philadelphia system;
particularly, their parents needed to be locally born for such learning to take place. What this amounts
to is that if a close-knit community network structure loosens and members become mobile, the
social prerequisites for supporting highly localized norms disappear, and dialect leveling takes place.
Thus, not only does a community's sense of distinctiveness become redundant as network ties loosen
(a social and ideological issue), but from a psycholinguistic perspective speakers lack the extensive
and regular input needed to maintain localized norms.

Such norms are sometimes complex; for example, Belfast speakers whose networks are relatively
loose-knit reduce the number of linguistically conditioned allophones of /a/ by eliminating the
extreme back and front variants characteristic of the vernacular system, often converging on a very
narrow area of vowel around the centre of the vernacular range (Milroy 1982, Milroy 1999). Thus,
close-knit networks may be viewed not only as social and sociolinguistic support mechanisms which
facilitate the construction and maintenance of local distinctiveness; from the point of view of the
language learner, they also provide the intensive input required to master complex, localized
linguistic structures which lack the support of institutional models. Leveling, which from this cognitive perspective can be viewed as a simplification strategy, takes place when such input is no longer
present. Trudgill (1989, i992) and Schilling-Estes (2000) provide relevant discussions of the social
conditions in which both simplification and structural complexity flourish.

We turn now to consider more specifically the links between mobility, social network structure, and
social class. Following Giddens (1989: 205-73), class is viewed here as one of four systems of
stratification which promote inequality in society. While the other three (slavery, caste, and estates)
depend on institutionally sanctioned inequalities, class divisions are not officially recognized, and
since an individual's class position is to some extent achieved, class stratification is accompanied by
varying degrees of mobility. Issues of power inequalities between groups and individuals are raised in
this discussion, which so far have only been touched upon.

Different types of network structure seem to be broadly associated with different social classes:
loose-knit networks with the socially and geographically mobile mainly middle classes, and close-knit
ties with very low status and very high status speakers. In terms of the predictions of the weak tie
model of change discussed above, this association is consistent with Labov's principle that innovating
groups are located centrally in the social hierarchy, characterized as lower-middle or upper-working
class (i 980: 254). The question then arises of how an integrated model of change and variation might
be constructed which takes account of the relationship between social class and social network
structures. Such an integration is desirable, since the association of different network types with
different social class groups is not arbitrary, but springs from the operation of large scale social,
political and economic factors (contra Guy 1988, who views network and class as unrelated, but
pertaining respectively to a micro- and macro-level of analysis).

Traditionally, sociolinguistics has assumed a consensus model of class, where the community is said
to be fundamentally cohesive and self-regulating. Yet, the vitality and persistence of nonstandard
vernacular communities highlighted by network studies is more readily interpreted as evidence of
conflict and division than of consensus. Accordingly, Milroy and Milroy (1992) argue that a dynamic
model of class as a process which splits the community into subgroups (characterized by different
orientations to work, leisure and family) is helpful in constructing an integrated theory of variation
and change. Hojrup's (i 983) analysis of these subgroups as characterized by different lifemodes with
different network structures “falling out” from those lifemodes is proposed as an approach which links
the variables of class and network in an illuminating way.

With the link between social class and network structure as their point of departure, Kerswill and
Williams (1999) have recently investigated the relationship between social class, mobility, and
susceptibility to change by comparing the language behavior of low and high mobility speakers of
different social statuses in the English towns of Reading and Milton Keynes. They conclude that
network structure has the predicted effect-that is, close-knit networks maintain localized norms,
while loose-knit networks facilitate change. However, they argue that the variables of class and
network need to be considered independently, given the different language behaviors of mobile high
status and mobile low status groups.

While the relationship between class, network, and mobility is evident, its precise character is as yet
unclear as are the linguistic outcomes associated with interactions between these social variables.
However, since they are constructed at different levels of abstraction, it is likely that a two-level
sociolin-guistic theory would be helpful. Such a theory should link the small-scale networks where
individuals are embedded and act purposively in their daily lives with larger-scale social structures
which determine relationships of power at the institutional level. The different sociolinguistic patterns
associated with both strong and weak ties would need to be considered, with attention to recent work
on the sociolinguistics of mobility. For, while strong ties give rise to a local cohesion of the kind
described by network studies of close-knit neighborhoods such as those in Belfast or Detroit, they
lead also to overall fragmentation in the wider community. Conversely, it is weak ties which give rise
to the linguistic uniformity across large territorries such as that described by Chambers in Canada,
Labov in the United States, and Trudgill et al. (2000) in New Zealand. The social dynamics underlying
both diversity and uniformity lie at the core of an accountable theory of language variation and
change.

23. The Speech Community.
PETER L. PATRICK.
Subject Sociolinguistics » Language Variation and Change.

The speech community (SpCom), a core concept in empirical linguistics, is the intersection of many
principal problems in sociolinguistic theory and method. I trace its history of development and
divergence, survey general problems with contemporary notions, and discuss links to key issues in
investigating language variation and change. I neither offer a new and correct definition nor reject the
concept (both misguided efforts), nor exhaustively survey its applications in the field (an impossibly
large task).
1 General Problems with Speech Community as a Concept
Every branch of linguistics that is concerned with representative samples of a population; that takes
individual speakers or experimental subjects as typical members of a group; that studies langue as
attributable to a socially coherent body (whether or not it professes interest in the social nature of
that body); or that takes as primitive such notions as “native speaker,” “competence/ performance,”
“acceptability,” etc., which manifestly refer to collective behavior, rests partially on a concept
equivalent to the SpCom. Linguistic systems are exercised by speakers, in social space: there they are
acquired, change, are manipulated for expressive or communicative purposes, undergo attrition, etc.
Whether linguists prefer to focus on speakers, varieties or grammars, the problem of relating a
linguistic system to its speakers is not trivial.
In studying language change and variation (geographical or social), reference to the SpCom is
inescapable, yet there is remarkably little agreement or theoretical discussion of the concept in
sociolinguistics, though it has often been defined. Some examples from research reports suggest the
degree of its (over-)extension (Williams 1992: 71).
The term “SpCom” has been used for geographically bounded urban communities, both large
(Philadelphia; Labov 1989) and small (Anniston, Alabama; Feagin 1996); for urban neighborhoods
(“Veeton” in Kingston, Jamaica; Patrick 1999) and subgroups-Belfast vernacular speakers (Milroy and
Margrain 1980, but see Macaulay 1997: 15) and “the French-speaking minority of Ontario,
Canada” (Mougeon and Beniak 1996: 69). It has been denied for other cities (London; Wardhaugh
1998: 123) but used for Anglo-Saxon England (Labov 1982: 35), for urban immigrants, as distinct
from both their source and target groups (Kerswill 1994), and for the “national unity of a
people” (Dittmar 1976: 106). Cutting across geographic and class lines, it has been used of very
general assemblages such as children (Romaine 1982: 7) and women (Coates 1993: 140), as well as
specific and temporary ones such as members of ajury (Durant 1999).
For rural populations, it has been used to pick out named settlements of Warlpiri speakers (Bavin
1989), but also for a discontinuous, larger region-the Caeltacht-in Ireland (Watson 1989) where

speakers do not define their communities in linguistic terms. Joly (1 981) calls the Afro-Hispanic
