Boundary and Annexation Survey (BAS) FAQs

BAS 2014 Suspension Information

Information about the suspension of the 2014 Boundary and Annexation Survey can be found on our Suspension of the 2014 BAS page.

Who authorized the survey?

The Boundary and Annexation Survey is authorized by Section 6 of Title 13 of the United States Code Census. The Office of Management and Budget (OMB) approves the survey materials. The current valid OMB control number is: OMB No. 0607-0151; approval expires on 12-31-2015. The BAS is a voluntary survey.

How is the information used?

The BAS information is used to provide an appropriate record for reporting the results of the decennial and economic censuses, and annual estimates and surveys such as the Population Estimates Program and the American Community Survey.

In compliance with the Office of Management and Budget, Circular A-16, the BAS supports the spatial data steward responsibilities of the Geo.Data.gov Link to a non-federal Web site and the National Map by updating the inventory of and boundaries for governmental units.

Will my government be surveyed?

The Census Bureau surveys all federally recognized American Indian areas, governmental counties (and equivalent areas), incorporated places, and governmental minor civil divisions (MCDs). This survey includes approximately 40,000 entities and is conducted every year to provide the geographic support needed for the American Community Survey. The number of entities included in the BAS in a particular year may vary after 2010 depending on funding and the needs of the Census Bureau in fulfilling the requirements for its censuses and surveys.

As part of our geographic partnership program, the Census Bureau has entered into several agreements with state and county governments. These agreements most commonly modify the list of entitites invited to participate in the survey, where knowledge of local areas identifies only those governments known to have boundary changes. Alaska, Georgia, Kentucky, Maine, Massachusetts, Michigan, Minnesota, Utah, Wisconsin, and Puerto Rico currently have agreements with the Census Bureau. For a list of county agreements, please email geo.bas@census.gov.

When will I receive the survey?

We do not automatically mail BAS packages. Annual Response information for 2015 BAS will go out in the fall of 2014.

 

When is the survey due?

All participants should return their responses by March 1st in order to have their updates reflected in next year's data from the American Community Survey and Population Estimates Program.

What if I have no boundary changes to report?

If your entity does not have any changes to report for this BAS cycle, you may notify the Census Bureau by e-mailing geo.bas@census.gov, returning the Annual Response Form, or returning the paper No Change Postcard that was included in your BAS package. If you choose to notify the Census Bureau via e-mail, please type "no boundary changes" in the subject heading and provide the following contact information for your Highest Elected Official and, if different, the BAS contact:

  • Name
  • Title
  • Entity Name
  • Mailing Address
  • Phone and Fax number
  • Email Address

How do I submit my response?

There are various ways to respond to the BAS. The Response Methods page provides further information.

Can a county report for entities within its boundaries?

The Census Bureau includes counties in the BAS so that you may report any changes to your county boundary as well as review the BAS form for the functional status of governments within your county. County reviewers are not required to report boundary changes for the jurisdictions within their county.

If you are interested in reporting changes for place or MCD governments within your county, the Census Bureau also offers consolidation agreements. At the county level, a county government can provide updates for their county boundary, as well as for entities within the county that agree to the consolidation. Counties participating in a consolidation agreement are required to obtain the permission of the entities for which they will report. (If your state has legislation in place requiring governments to report boundary changes to the county, then we ask only that you provide us this documentation.). The Census Bureau will not mail the affected entities a BAS package next year or any subsequent year after an agreement has been completed.

How do I report a new incorporation?

If you are a newly incorporated place and would like to participate in the BAS, please contact geo.bas@census.gov. In order to participate in the BAS, the Census Bureau will need:

  • A copy of the official new incorporation papers, including date of incorporation
  • A map indicating the boundaries of the new incorporation
  • Contact information for the highest elected official and a contact for the BAS
