  1. CENSUS GEOGRAPHY WORKSHOP Tim McMonagle Geography Los Angeles Regional Census Center

  2. Topics • Census Geography • Demographic Data • MAF/TIGER Data Base (MTDB) • TIGER/Line Files • Joining TIGER and Demographic Data • Count Question Resolution Program • Future for MTDB? • New American Fact Finder Mapping

  3. Census Geography

  4. The Role of Geography in the Decennial Census • Geography provides the framework for the collection, tabulation, and dissemination of Census Data • Success of the Census rest not only on collecting data, but also linking data to correct geographic areas • Anyone using Census Data should have some knowledge of Census Geography

  5. Hierarchy of Census Geography

  6. Urban/ Rural Classification

  7. Urban / Rural • For the 2010 Census, an urban area will comprise a densely settled core of census tracts and/or census blocks that meet minimum population density requirements, along with adjacent territory containing non-residential urban land uses as well as territory with low population density included to link outlying densely settled territory with the densely settled core. • The Census Bureau identifies two types of urban areas: -Urbanized Areas (UAs) of 50,000 or more people -Urban Clusters (UCs) of at least 2,500 and less than 50,000 people. • “Rural” encompasses all population, housing, and territory not included within an urban area.

  8. Urban / Rural (Urban Areas) – Schedule • November 22, 2010 – Public comment period ends for proposed criteria published in Federal Register • http://www.census.gov/geo/www/ua/urbanruralclass.html • First quarter of 2011 – Final criteria published in Federal Register • March-December 2011 – delineation • Spring 2012 – Federal Register notice listing final Urban Areas • April 2012 – Urban/Rural TIGER/Line Shapefiles • October 2012 – SF-1 Urban/Rural Update • Late-2013 – ACS publishes data for 2010 Urban Areas

  9. Urban / Rural • Additional information and a link to the Federal Register announcement is at: http://www.census.gov/geo/www/ua/2010urbanruralclass.html

  20. 2010 Census Advance Group Quarters Summary File

  21. Advance Group Quarter Summary File • An early version of Table P-42 from the 2010 Census Summary File 1, showing seven types of group quarters • Institutional Group Quarters - Adult correctional facilities - Juvenile correctional facilities - Nursing facilities - Other institutional facilities • Non-institutional Group Quarters - College/University student housing - Military quarters - Other non-institutional facilities • No characteristics of the group quarters are provided.

  22. Advance Group Quarters Summary File (Cont.) • Early release for use in Redistricting and the Count Question Resolution program. • Table is only available via the FTP site. • Flat ASCII files by state • Provide Microsoft Access shells to help with importing and extracting the data. • Link to files and information about the files at the Redistricting Data Office data site: http://www.census.gov/rdo/data/

  23. 2010 Census Geographic Products

  24. TIGER/Line Shapefiles

  25. MAF/TIGER Data Base (MTDB) • Replaces and combines Master Address File (MAF) and Topologically Integrated Geographic Encoding and Reference (TIGER) system databases • Nationwide – not divided by county • Oracle Spatial 10g database

  26. MAF/TIGER Accuracy Improvement Program • Aligning the MAF/TIGER database with GIS/Imagery maintained by state/local/tribal partners/federal/private in order to implement more programs in a digital environment • Improve spatial accuracy to allow the Census to use GPS handheld devices to collect data accurately • Support the Administrations Geospatial One Stop e- government initiatives, make data publically available

  27. Role of TIGER • Assignment of location codes to addresses for data collection • Geographic structure for tabulation and publication • Cartographic products to support field operations, participant programs, collection and publication

  28. What are TIGER/Line Shapefiles? • Extracts of selected geographic and cartographic information from MTDB. • Nationwide coverage • Contains no sensitive data • Are designed for use with GIS • Contains geographic linear, areal, and point features, including attribute information • Geographic entity boundaries • The legal and statistical areas for which Census tabulates data

  29. File Naming Convention The name of each file is: tl_2010_<extent>_<layer>_<ext> • tl- TIGER/Line • 2010- version • extent - 2 digit state FIPS code - 5 digit state county FIPS code • layer- type of geography or feature 10 at the end = 2010 census geography 00 at the end = 2000 census geography • ext – file extension

  38. CQR Summary • Scope • Timing • Challenge Types • Documentation Requirements • Challenges Results - Successful -Unsuccessful

  39. Scope • The Census Bureau’s 2010 Census Count Question Resolution (CQR) Program provides state, local, and tribal officials, or their designated representatives, in the United States and Puerto Rico a process to challenge the census counts of housing units, group quarters, and group Quarter population.
