BAS Schedule
BAS Schedule
The Boundary and Annexation Survey (BAS) is an annual survey which follows the activity and outreach schedules below. If you have any questions regarding this schedule, please Contact Us.
Activity Schedule
| Date | Activity |
|---|---|
| January 1 | Legal boundary changes must be legally in effect on or before this date to be reported in the current survey year. |
| January to May | The Census Bureau conducts BAS. Eligible governments respond to BAS indicating if they have legal boundary, census designed place (CDP), linear feature, or contact updates to report. Those with updates can choose to create their submission using the Census Bureau's BAS Partnership Toolbox, Geographic Update Partnership Software (GUPS), GUPS Web, or paper maps. |
| March 1 | Legal boundary changes returned by this date will be reflected in the American Community Survey and Population Estimates Program data and in next year's BAS materials. |
| May 31 | Legal boundary changes returned by this date will be reflected in next year's BAS materials. If time permits, boundary corrections returned by this date may also be reflected in next year's BAS materials. |
BAS Outreach
| Date | Activity |
|---|---|
| Early January | The Census Bureau notifies eligible governments about BAS through email. Eligible governments are contacted through email to determine if they have legal boundary, CDP, linear feature, or contact updates to report. Any eligible government without an email on file with the Census Bureau will be contacted by phone and asked to provide their response. |
| Mid-February, Mid-March, and Mid-April | The Census Bureau conducts nonresponse follow-up for BAS through email. Eligible governments that have not responded to annual response, along with those that indicated they have updates to report but have not yet submitted those updates, are contacted through email on up to three occasions. |
