The reapportionment of House seats will be announced on Dec. 21, the Census Bureau has announced.

The bureau is set to release its first set of 2010 census data at a press conference at the National Press Club that morning.

The numbers will include the resident population for the country, and broken down by state, as well as the congressional apportionment totals for each state.

These numbers are eagerly anticipated because each state will redraw its congressional boundaries based on the census reapportionment numbers.
