Where are we with Urbanized Areas?
Getting Closer1. 2010 Census Completed2. Criteria Finalized3. Census Bureau does it
72% households mailed back forms77% of 47 Million NRFU households visited

Where are we with Urbanized Areas?
4
Urban Areas
Urbanized Areas(50,000+)circa 1950
Urban Clusters(2,500 to 49,999)
circa 2000
Some Background
http://rtc.ruralinstitute.umt.edu/
5
Urban Areas (2000)
Composed of CORE census block groups or blocks that have a population density of at least 1,000 people/square mile and the surrounding census blocks that have an overall density of at least 500 people/square mile.
Generalized Definition

Transportation Perspective
(Census Defined) Urbanized Area (UZA)
Federal-Aid (Adjusted) Urban[ized] Area (FAUA)
Metropolitan Planning Area (MPA)
Non-Attainment Area

Don’t Let Names Confuse You
Federal-Aid (Adjusted) Urban[ized] Area (FAUA)
Urban Area Boundary (UAB)
Adjusted Urbanized Area (AUZA)

Boundaries - the Important thing

(Census Defined) Urbanized Area (UZA) - Population + $$$
Adjusted Urbanized Area (AUZA) - Functional Class
Metropolitan Planning Area (MPA) - MPO Jurisdiction
Non-Attainment Area

Why is the UA so Important?
Census Defined Urbanized Area (UA) - Population + $$$

10
Why is the AUZA so Important?
Adjusted Urbanized Area (UZA) - Functional Class
FEDERALY -- It’s Not so important, But it Was at one timeSpeed LimitsRoad FundingData ReportingFunctional ClassBillboard Control ???
For States and MPOs it’s a whole Different Story
11
Why is the MPA so Important?
Metropolitan Planning Area (MPA) - MPO Jurisdiction
Sets MPO Area of Responsibility~ for Planning~ for Programming~ Overall Governance
12
Some Implications for Transportation
• New / Retired MPOs• New / Retired TMAs• Expanded MPOs & TMA• Changed Roadway Classifications• Data Reporting and reports• Funding and Financial Issues• Outdoor Advertising

What’s an MPO? A TMA?

Timing
2009 SAFETEA-LU expired
???? New Bill Expected (2011)
2010 Fed Register-Comments on UA criteria
2011 UAs Defined (Springtime)
2012 UAs Out (Springtime)

Metropolitan Statistical Areas
Metropolitan and Micropolitan Statistical Areas, Metropolitan Divisions, Combined Statistical Areas
When will new MSA be defined?

Two Planning Related Geographies
PUMAs
TAZs / TADs
17
PUMAs? -- What are they?
PUMAs are the zones used for 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.

Standard Tabs
PUMS Records

Why are PUMAs Important?
Normal ACS Annual Data
● Annual Data
● 65K+
● Note the areas in gray
● We call this Swiss Cheese
NE Illinois (2008 pop estimate)
Chicago
19
Why are PUMAs Important?
NE Illinois (PUMAs)
PUMAs are a Tabulation Area for Annual ACS Data
● Represent 100K
● Complete Coverage
● Smaller than Counties
● NO Swiss Cheese
20
How many PUMAs should this area have?
http://www.census.gov/geo/www/maps/puma5pct.htm
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).
