2012 Boundary and Annexation Survey (BAS): Schedule

The Census Bureau is mailing an advance response letter to all federally recognized American Indian tribes with reservations or off-reservation trust land, governmental counties (and equivalent areas), incorporated places, consolidated cities, and governmental Minor Civil Divisions (MCDs) in December of 2011 and January of 2012.

All BAS respondents that wish to submit boundary changes, corrections, or feature updates must request maps from the Census Bureau or download materials from this web site. All 2012 BAS maps, forms, letters and user guides are available for download. Participants who wish to have paper maps and/or materials delivered must notify the Census Bureau prior to February 15, 2012.

The Census Bureau must receive responses to the 2012 BAS before March 1, 2012 to be included in the Population Estimates Program and the American Community Survey.
