Wisconsin Boundary and Annexation Survey (BAS)
The U.S. Census Bureau conducts the Boundary and Annexation Survey (BAS) annually to collect information about selected legally defined geographic areas. The BAS is used to update information about the legal boundaries and names of all governmental units in the United States. 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.
To reduce the burden on local governments and avoid duplication of efforts, the Census Bureau offers consolidation agreements to counties that are interested in submitting boundary changes for the legal governments (incorporated places and minor civil divisions) within their jurisdiction. The consolidated BAS (CBAS) program allows counties to report boundary and feature changes for some or all of the legal governments within their county. Once a local government agrees to the consolidation, the local government will no longer receive BAS materials. Instead, the county BAS respondent will be responsible for providing the Census Bureau with all boundary updates.

LTSB Boundary Annexation Survey Tool
This LTSB tool will be made available at no charge to update the spatial accuracy of municipalities in TIGER. The tool is designed and built within ESRI based products.
It is important to note that this tool:
- Will not change your local dataset. It will only compare it to the Census Bureau data.
- Will not be submitting a change file to the U.S. Census Bureau, it will only create one based on a comparison of your local data.
- Any local datasets used will be made part of a statewide layer of information available on our website.
If you wish for your local dataset to not be a part of the statewide layer, please let us know.
