1 2020 Census Participant Statistical Areas Program (PSAP) Overview Joshua Coutts Geography Division U.S. Census Bureau

2 2020 Census PSAP Allows invited participants to review and update selected statistical area boundaries for 2020 Census data tabulation using Census Bureau criteria and guidelines. The Census Bureau uses the resulting statistical areas for the 2020 Census, the American Community Survey (ACS), and other censuses and surveys. 2

3 Primary Participating Organization (PPO) PSAP s single point of contact for each participating area Work is organized by county, but a single PPO may be responsible for more than one county 2010 participants are invited by default finalizing invitations now Responsibilities Receiving and processing materials (maps, etc.) Can designate separate technical lead (PPT) Outreach and point of contact for local data stakeholders Consolidating stakeholder requests Delivering final project plans Verification sign-off 3

4 2020 Census PSAP Statistical Geographies Standard statistical geographies include: o Census tracts. o Block groups. o Census designated places (CDPs). o Census county divisions (CCDs) in selected states. Tribal statistical geographies include: o Tribal census tracts (TCTs). o Tribal block groups (TBGs). o Census designated places (CDPs). o Tribal Designated Statistical Areas (TDSAs). o State Designated Tribal Statistical Areas (SDTSAs). o Alaska Native village statistical areas (ANVSAs). o State reservations (legal entities). o Oklahoma tribal statistical areas (OTSAs). and associated tribal subdivisions. 4

5 2020 Census PSAP Criteria No substantial changes to criteria from Statistical geographies are recognizable in: o Concept and purpose. o Coding and naming conventions. o Types of boundary features permitted. Removal of special land use area measurement thresholds 5

6 Block Groups Type Characteristics National coverage? Nests within: Population threshold Housing Threshold Standard county based and tribal reservation based Form the geographic framework within which census blocks are numbered. Smallest area for which demographic statistics are produced from the American Community Survey (ACS). Yes Census tracts Minimum: 600 Maximum: 3000 Minimum: 240 Maximum: 1200 Special land use Distinguish areas of little or no population that have a specific type of land use AND are coextensive with a special land use census tract. Large water bodies. No Census tracts Little/None or must be within standard block groups thresholds. Area measurement thresholds are no longer applicable for special land use block groups. 6

7 2020 Census PSAP Delineation Substantial changes to the review and update process of these statistical geography boundaries Statistical geographies reviewed and updated by Census Bureau (Pre-SAP) for adherence to: o Published criteria and guidelines. o Coding and naming conventions. o Optimal boundary feature use. Invited participants will have the following options: o Accept the Census Bureau s 2020 Census proposed statistical areas. o Update the 2020 Census proposed statistical areas. o Use the 2010 Census statistical area geography as a base to make updates. 7

8 2020 Census Pre-SAP Process Census staff conducted an internal review of: o Census tracts, o Block groups, o CCDs, CDPs, and tribal statistical geographies. Planned Pre-SAP updates are reviewed and implemented prior to 2020 PSAP product creation. 8

11 CDP Identification and Delineation (HQ) Lillian, AL Numerous named features (restaurants, churches, post office) recognition on county parcel viewer as a place. From the County Parcel Viewer: Proposed boundary. Parcels and linear features will make up most of the boundary. Tract/BG boundaries (not shown) will be used in the water as the southern and eastern boundaries

12 CDP Review Approximately 10,000 current CDPs for review. Checking for gaps, slivers, and other necessary boundary updates. 12

19 Primary Participant Expectations To review and update statistical areas for the Conduct outreach within their participation area with other data organization. Solicit input on draft delineations from local data stakeholders. County based participants will use GUPS to review and modify their updates. Tribal participants may use paper maps to provide updates. Participate in final verification processes. Answer questions from local stakeholders. Allow for the posting of their contact information on the USBOC PSAP website. 19
