CONGRESSIONAL DISTRICTS
110th Congress (January 2006 - January 2008)
The Constitution prescribes Congres-
sional
apportionment
based on
decennial census population data. Each
state has at least one Representative, no
matter how small its population. Since
1941, distribution of Representatives has
been based on total U.S. population, so
that
the average population per
Representative has the least possible
variation between one state and any
other. Congress fixes the number of
voting
Representatives
at
each
apportionment. States delineate the
district boundaries. The first House of
Representatives
in 1789 had 65
members; currently there are 435.
There are non-voting delegates from
American Samoa,
the District of
Columbia, Guam, Puerto Rico, and the
Virgin Islands.
