The purpose of the BAS state agreements is to coordinate the sharing of information and resources between the U.S. Census Bureau and the state governments in collecting boundary information for selected legally defined geographic areas. Through this partnership with the state governments, the Census Bureau aims to reduce the duplication of effort among the various levels of government and the cost burden associated with the annual BAS.
The Census Bureau currently maintains BAS state agreements with eight states and is working to establish new agreements with interested state governments. Two types of BAS state agreements are available to states that enforce laws requiring local governments to report all boundary changes to a state agency. Under the first type of agreement, the state reports boundary changes for all incorporated places, minor civil divisions (if applicable), and counties within its jurisdiction to the annual BAS. The Census Bureau currently maintains this type of state agreement with Alaska, Kentucky, Louisiana, Maine, Massachusetts, and Utah. Under the second type of agreement, the state provides the Census Bureau with a list of local governments that reported boundary changes to the state. The Census Bureau uses this list to target those local governments for the BAS. The Census Bureau currently maintains the second type of agreement with Georgia and Michigan.
If your state is interested in establishing a BAS state agreement, please contact the Legal Areas Team of the Census Bureau’s Geography Division by phone at 301-763-1099 or by email at firstname.lastname@example.org. Please note that the Census Bureau can only establish BAS state agreements for states that require local governments to report boundary changes to a state agency.
