  2. 2010 Census Day - APRIL 1st Short Form Population count Age, Race, Sex, Owner/Renter

  4. What is your Local Response Rate? http://2010.census.gov/2010census/take10map/

  5. Urban Boundaries Census Defined Urban Area (UA) Adjusted Urbanized Area (UZA) Metropolitan Planning Area (MPA) Non-Attainment Area http://www.fhwa.dot.gov/planning/census/faqa2cdt.htm

  6. Boundaries - the Important thing Census Defined Urban Area (UA) - Population + $$$ Adjusted Urbanized Area (UZA) - Functional Class Metropolitan Planning Area (MPA) - MPO Jurisdiction Non-Attainment Area The Letters UZA and UA often get mixed up http://www.fhwa.dot.gov/planning/census/faqa2cdt.htm

  7. Boundaries - some names people use Census Defined Urban Area (UA) Census Urbanized Area (UZA) Adjusted Urbanized Area (UZA) Federal Aid Urban Area (FAUA) FHWA Adjusted Boundary Adjusted Urban(ized) Area Metropolitan Planning Area (MPA) Planning Area MPO Boundary

  8. What’s an MPO? NARC- Status Quo AASHTO -Somewhat Vague FHWA - Internal House - T+I Committee, HR ____ Senate - 100K - Threshold Grandfathering 200K - Project Selection Authority 1 Million+ Special Funding and Requirements http://www.ampo.org/assets/685_finalampopdfoverviewappro.pdf

  9. 2000 density based, automated process, identified urban clusters (2,500 pop), ignored place boundaries and built from Census Blocks 2010 Census Bureau still deciding process Investigating use of place of work data via ACS, reviewing land use covers and digital elevation maps and satellite imagery, thinking about using household densities and building from Census Tracts. Look for criteria for defining urbanized areas and clusters in Spring 2010 in Federal Register Census Defined Urban Area (UA) http://www.edthefed.com/uza/UA_Update.pdf feb. 2009

  10. Webinar and other Materials Q/As from Webinar http://ctpp.transportation.org/

  11. Some Final Words on UAs http://www.fhwa.dot.gov/planning/census/faqa2cdt.htm

  12. Metropolitan Statistical Areas Metropolitan and Micropolitan Statistical Areas, Metropolitan Divisions, Combined Statistical Areas Mega Regions

  13. PUMAs? -- What are they? Public Use Microdata Sample PUMSdata is based on individual census records and is available only at large geographic areas. Think of the PUMS dataset as the raw, disaggregate census sample data, at a large enough geographic level necessary to protect the confidentiality of the census respondent. Standard Tabs ACS Sample PUMS Records PUMAs are the zones used from PUMS data

  14. Chicago Why are PUMAs Important? NE Illinois (2008 pop estimate) Let’s Look at Annual Data • Annual Data • 65K+ • Note the areas in gray • We call this Swiss Cheese

  15. Why are PUMAs Important? NE Illinois (PUMAs) Tabulation Area for ACS • Represent 100K • Complete Coverage • Smaller than Counties • NO Swiss Cheese

  16. How many PUMAs should this area have? City of Chicago 2000 PUMAs Why are PUMAs Important? - Defines areas for analysis - Tabulation Area for ACS Who Defines Them? - The Community - Led by State Data Center When are They Defined? - Summer 2011 - Criteria out Spring 2010 2,896,016 (2000 Pop) http://www.census.gov/geo/www/maps/puma5pct.htm
