CENSUS
US State Populations
CENSUS
is a dataset directory which
contains some census data.
The US Constitution mandates that the apportionment of the House
of Representatives be based on the population of the states, and
that a census of state populations be made every ten years for
this purpose.
The files here contain some rough, recent census results for the states.
With a little care, this information can be used to study various
schemes for "fair" distribution of the seats in the
House of Representatives.
