larger  units   accompanied by  discrimination  and assimilation    pressure.
Continuing  migration   has concomitantly   worked  as  a   countertendency,    making
many    urban   environments    more    ethnically  diverse.    Yet the conflict    potential
associated  with    ethnic  intergroup  relationships   remains,    as  the more    inclusive
identity    of  the big city    does    not always  displace    the less    inclusive   ‘heritage’
identities  of  migrants,   or  their   marginalization by  the dominant    majority.   As  a
response,   self-segregation    is  a   noticeable  trend   among   many    groups  whose
members embrace ethnic  identities  to  counterbalance  the individualization   of
urban   life    and reduce  the risk    of  being   nobody.
Conclusions
The increased   presence    of  immigrants  in  urban   centres of  the West    has raised
public  awareness   of  ethnic  identity.   Cultural    anthropologists understand  this    kind
of  identity    as  distinguishing  population  groups  whose   members agree   on  traits
that    set them    apart   from    others, notably race,   language,   and religion.   While
members of  groups  thus    defined tend    to  think   of  these   criteria    as  fixed,  they    are
social  rather  than    natural.    Therefore,  ethnic  identities  can adjust  to  changing
circumstances,  although    the members who affiliate   with    an  ethnicity   may be
convinced   of  its intransience.
