Participant Statistical Areas Program

The 2020 Census Participant Statistical Areas Program (PSAP) enables invited participants to review and update selected statistical area boundaries for 2020 Census data tabulation following U.S. Census Bureau guidelines and criteria. The Census Bureau also will use the statistical areas defined for the 2020 Census to tabulate data for the annual American Community Survey (ACS) estimates and the Economic Census.

The statistical geographies available for review under the 2020 Census PSAP include:

  • Census Tracts
  • Block Groups
  • Census Designated Places (CDPs)
  • Census County Divisions (CCDs)

The goal of the PSAP is to define meaningful, relevant statistical areas so that data users can obtain meaningful, relevant small area and place-level statistical data. These data are used to:

  • Prepare grant applications to fund community and regional development, education, agriculture, energy, and environmental programs, as well as other needed community improvements and enhancements.
  • Plan for future community needs. The next opportunity to review and delineate statistical areas is planned for the 2030 Census.

PSAP in the Triangle

TJCOG was designated by the U.S. Department of Commerce as a primary PSAP participant for the 7-county Triangle region, as well as both Metropolitan Planning Organizations (MPOS) - North Carolina Capital Area MPO (NC CAMPO) and Durham-Chapel Hill-Carrboro MPO (DCHC). 

As the primary PSAP participant, TJCOG delineated the following counties: Chatham, Durham, Johnston, Lee, Moore, Orange, and Wake. In Spring 2019, TJCOG worked with city and county planners and GIS specialists from each county to determine if the proposed changes were acceptable. TJCOG submitted these changes to the U.S. Census Bureau in May 2019 on behalf of the Triangle region.

Opportunity for final comment on the update of census tracts, block groups, and census designated places will occur in January 2020. 

More information on the PSAP can be found on the U.S. Census Bureau's website.
