Governmental Unit Boundaries

Various Census Bureau products available on the Internet display the Governmental Unit Boundaries of states, counties, incorporated places, county subdivisions, American Indian areas, Alaska Native areas, and Hawaiian home lands. These boundaries are collected through the Census Bureau's Boundary and Annexation Survey (BAS) which contacts the highest elected official (or designee) for changes to boundaries the most common of which are annexations and detachments. The boundaries shown on Census Bureau maps and in Census Bureau geographic products are for Census Bureau statistical data collection and tabulation purposes only; their depiction and designation for statistical purposes does not constitute a determination of jurisdictional authority or rights of ownership or entitlement. To seek a correction of this information, the affected person should contact the office of the highest elected official. The highest elected official (or designee) should contact the Census Bureau using the BAS toll-free number 1-800-972-5651 to obtain the necessary forms and maps to report the correction, or they may report the correction when responding to the next BAS. The affected individual also should send an email message to the Census Bureau at geo.tiger@census.gov providing the following documentation: contact information; description of the information to correct; and specific recommendations for how and why the information should be corrected. The Census Bureau will ascertain if the entity provides the correction in the next BAS, and report to the affected person whether or not the correction was received.
