January 14, 2015 – The highest elected official or other administrative staff in your community may have recently received a correspondence from the U.S. Census Bureau related to the Boundary and Annexation Survey (BAS) Program.  This is an important opportunity for your community to ensure that its boundaries are correct in the Census Bureau files.  The Census Bureau uses the boundary information collected in the BAS to tabulate data for the decennial and economic censuses, and annual estimates and surveys such as the Population Estimates Program and the American Community Survey.  More information is available in the handout below.

We are happy to assist in navigating this program.  Please contact Lisa J. Miller, Data/GIS Director, (309) 793-6302, extension 133 or This email address is being protected from spambots. You need JavaScript enabled to view it..
