The apportionment counts will be delivered to the President within nine months of Census Day (on or before December 31, 2010), as required by law. This report will show the apportionment population counts, by state, and the number of seats in the US House of Representatives apportioned to each state.
Public Law (P.L.) 94-171 requires the Census Bureau to provide only counts of the total population for a variety of geographic areas to be used for the redistricting process. In addition, other data items such as race, ethnicity, voting age and housing unit tallies are included in this data set. P.L. 94-171 also requires that these data be delivered to each state no later than April 1, 2011.
Other 100-percent data products such as demographic profiles, summary files of aggregated data, and reports will be released on a flow basis from April 2011 through September 2013. Please see the link below for a more detailed schedule of products and release dates.
