Census Defined Urban Area (UA) - Population + $$$
Adjusted Urbanized Area (UZA) - Functional Class
Metropolitan Planning Area (MPA) - MPO Jurisdiction

Census Defined Urban Area (UA)
http://www.edthefed.com/uza/UA_Update.pdffeb. 2009
2000 density based, automated process, identified urban clusters (2,500 pop), ignored place
boundaries and built from Census Blocks
2010 Census Bureau still deciding processInvestigating 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

PUMAs? -- What are they?
PUMAs are the zones used from PUMS data
Public Use Microdata Sample
PUMS data 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.

Why are PUMAs Important?
Tabulation Area for ACS
● Annual Data
● 65K+
● Note the areas in gray
● We call this Swiss Cheese

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

PUMA Geography

City of Chicago 2000 PUMAs
2,896,016 (2000 Pop)
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
What is the CTPP?
CTPP is an umbrella program of dataproducts, custom tabulations, training, technical assistance, and research for the transportation community. CTPP uses data from U.S. Census Bureau, including American Community Survey (ACS).
