Classification
of
indigenous
peoples
of
the
Americas
is
based
upon
cultural
regions,
geography,
and
linguistics.
Anthropologists
have
named
various
cultural
regions,
with
fluid
boundaries,
that
are
generally
agreed
upon
with
some
variation.
These
cultural
regions
are
broadly
based
upon
the
locations
of
indigenous
peoples
of
the
Americas
from
early
European
and
African
contact
beginning
in
the
late
15th
century.
When
indigenous
peoples
have
been
forcibly
removed
by
nation-states,
they
retain
their
original
geographic
classification.
Some
groups
span
multiple
cultural
regions.
In
the
United
States
and
Canada,
ethnographers
commonly
classify
indigenous
peoples
into
ten
geographical
regions
with
shared
cultural
traits,
called
cultural
areas.[1]
Greenland
is
part
of
the
Arctic
region.
Some
scholars
combine
the
Plateau
and
Great
Basin
regions
into
the
Intermontane
West,
some
separate
Prairie
peoples
from
Great
Plains
peoples,
while
some
separate
Great
Lakes
tribes
from
the
Northeastern
Woodlands.
Indigenous
peoples
of
the
Great
Plains
are
often
separated
into
Northern
and
Southern
Plains
tribes.
