Census Redistricting Data to be released February 2011
The first data to be released from a Decennial Census is always the state Redistricting Data (P.L. 94-171) Summary File, named for the Public Law which requires it to be sent to the President by the end of January following the Census. The Census Bureau has issed a schedule of planned release dates for data products which indicates that the P.L. 94-171 file will be publicly released in February 2011.
The state redistricting file is always anxiously awaited, and is used by states to redraw Congressional District and other electoral distric boundaries based on population counts and apportionment laws. It tends to be controversial and fraught with accusations of gerrymandering by the party in control of the state legislatures.
