Singapore’s ethnic  classification  provides    an  example.    The British
administration  perceived   the colony’s    population  as  consisting  of  a   wide    variety
of  ‘races’ including   Cantonese,  Hokkiens,   Hylams, Khehs,  Straits-born    Chinese,
Malays, Sumatrans,  Javanese,   Buginese,   Boyanese,   Tamils, Malayalis,  Punjabis,
Pathans,    Sikhs,  Sindhis,    Europeans,  and Eurasians.  After   independence,   the
Singapore   government  fused   all of  these   into    four    groups, Chinese,    Malays,
Indians,    and Others. Like    the evidently   arbitrary   ‘Others’,   the remaining   three
categories  were    internally  heterogeneous,  but over    the decades this    classification
acquired    a   social  reality,    as  the Singaporeans    gradually   accepted    it  and
developed   a   sense   of  (Singaporean)   Indianness, Malayness,  and Chineseness.
The amalgamation    of  these   three   groups  has various consequences,   for example,
regarding   the languages   of  public  services    and instruction at  school. It
exemplifies the malleability    of  ethnic  boundaries  and at  the same    time,
ironically, underscores the tendency    of  socially    constructed ethnic  identities  to
assume  an  essential   quality to  their   adherents.  Singapore   has been    largely
successful  in  avoiding    community   strife  by  reducing    and ordering    difference.
Perhaps the administrative  classification  makes   everyone    realize that    it  involves
a   measure of  arbitrariness,  which   works   against exaggerated essentialism.
In  Singapore,  as  in  Europe  much    earlier,    the principal   thrust  of  ethnic  dynamics
was to  create  larger  groups. But this    is  not a   single  march   in  the direction   of
higher  levels  of  ethnic  integration.    While   Singapore   created more    inclusive
categories, China   moved   from    distinguishing  only    four    groups  in  addition    to  the
Han Chinese—Manchus,    Mongolians, Tibetans,   and Koreans—at  the beginning
of  the 20th    century,    to  fifty-six   officially  recognized  ethnic  minorities, at  the end.
Similar developments    occurred    in  independent India.  The constitution    of  1950
introduced  the term    ‘Scheduled  Tribes’,    of  which   the government  gradually
recognized  more    than    700.    The United  States  and Western Europe, too,
experienced an  ‘ethnic revival’,   in  which   subnational groups  were    increasingly
seen    as  indispensable   building    blocks  of  society.
Appreciation    of  ethnic  diversity   is  historically    contingent. The epoch   of
decolonization  after   World   War II  brought with    it  recategorizations,  both    in
newly   independent states  and in  Western European    countries   where   continuing
in-migration    motivated   new distinctions.   For instance,   Malaysia    introduced  the
category    Bumiputera  (literally  ‘sons   of  the land’)  to  distinguish Malays  and
other   indigenous  peoples of  South   East    Asia    from    Chinese and Indian
