Participant Statistical Areas Program

2020 Census PSAP

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.

2020 Census PSAP in the Triangle

 To reduce participant burden, the Census Bureau provided proposed 2020 Census tracts and block groups for review and update by Primary PSAP participants. Triangle J COG was the Primary PSAP Participant for the Triangle region and, as such, tasked with:

  • Notified stakeholders about the start of PSAP and requested input;
  • Organized meetings to discuss analytical needs and solicit suggested changes; and
  • Used existing methods for communicating with stakeholders.

Because of the decision to discontinue providing data for the Census Transportation Planning Products (CTPP) program and user-defined Transportation Analysis Zones (TAZs), transportation planners should be consulted during the PSAP delineation phase, particularly regarding special use census tracts and special use block groups. As such, TJCOG coordinated closely with both Metropolitan Planning Organizations (MPOs) – Durham-Chapel Hill-Carrboro (DCHC) and Capital Area MPO (CAMPO) – and the Triangle Area Rural Planning Organization (TARPO).

In Spring 2019, TJCOG coordinated the PSAP delineation phase in the following counties: Chatham, Durham, Johnston, Lee, Moore, Orange, and Wake. In July 2019, TJCOG submitted changes on behalf of these communities, MPOs, and RPO. In early 2020, TJCOG will coordinate the PSAP verification phase and review the 2020 statistical areas and submit corrections, in coordination with the counties, MPOs, and RPO.

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