U.S. Census Bureau Statistical Geographic Areas and the 2020 PSAP Program

Explore the U.S. Census Bureau's statistical geographic areas and learn about the Participant Statistical Areas Program (PSAP) for the 2020 Census. Discover the importance of defining these areas, their relationship with legal entities, and how the PSAP allows local participants to suggest modifications.

Presentation Transcript

  1. Overview of U.S. Census Bureau Statistical Geographic Areas and the 2020 Participant Statistical Areas Program (PSAP) Joshua Coutts Geography Division U.S. Census Bureau April 3, 2018

  2. Outline • What is U.S. Census Bureau statistical geography? • Why does the U.S. Census Bureau define statistical geographic areas? • Participant Statistical Areas Program (PSAP) entities and program details

  3. What is U.S. Census Bureau statistical geography? Geographic areas: • Defined solely for data collection, tabulation, dissemination, and analysis • Representing geographic concepts, such as urban, rural, metropolitan • Representing communities, localities, and other recognizable areas that do not have legally defined boundaries or are surrogates for legal entities

  4. Why does the U.S. Census Bureau define statistical geography? Need for data and information Counterparts to legal entities Provide finer spatial resolution Consistent and comparable entities for longitudinal analysis Entities designed to ensure statistical reliability, protect confidentiality of data

  5. Participant Statistical Areas Program (PSAP) A Decennial program that allows local participants, following Census Bureau criteria and guidelines, to review and suggest modifications to the inventory, boundaries, and names of statistical geographic areas. 2020 PSAP geography includes: • Census tracts • Block groups • Census designated places (CDPs) • Census county divisions (CCDs) • Tribal statistical geographic areas

  6. Geography Division Partnership Goals • Expand and encourage geographic partnerships with all sectors of government, the organizations that serve them, and the private sector • Develop and deploy new strategies to: • communicate more effectively with these groups • increase participation in geographic programs • effectively integrate the address list review program, street centerline update program, and boundary reporting programs that now exist as separate programs • Establish new partnerships that can be used to improve the accuracy, currency and coverage of the MAF/TIGER system.

  8. General Characteristics of PSAP Entities

  9. Geographic Area Relationships:Small Statistical Areas

  10. No Changes to Concepts or Criteria from 2010 All 2020 PSAP geographies are recognizable in: • Concept and purpose • Coding and naming conventions • Types of boundary features permitted Criteria and guidelines were revised to improve clarity and to standardize informal practices and interpretations of previous operations. 10

  18. PSAP Participants • Technical PSAP Contact • Conducts the PSAP review for the delineation and verification phases. • Submits updates to the Census Bureau. • Primary PSAP Contact • Coordinates the PSAP review and update activities. • Regional planning directors, executive directors, councils of governments, etc. Any interested party may submit requests for boundary updates to the primary PSAP contact

  21. Presentation Outline Proposed NGDA Dataset Removal • NGDA Theme: Transportation • NGDA Theme Lead: Raquel Wright, DOT, Bureau of Transportation Statistics, raquel.wright@dot.gov • NGDA Dataset: 2010 Census Traffic Analysis Zone (TAZ)

  22. Presentation Outline Proposed NGDA Dataset Removal • Justification • A2020 Census TAZ Delineation Program would exceed $2.5 million, which would comprise more than half the CTPP Program’s 5-year budget. Non-standard geographies are disproportionately more expensive to tabulate than standard geographies—resulting in higher costs for lesser quality data. • Archive • Dataset will remain available via the US Census Bureau’s website and discoverable on Data.gov.
