Where are we with Urban Areas?
Getting Closer
Criteria Finalized in Fed Reg (Sept. 2011)http://www.census.gov/geo/www/ua/2010urbanruralclass.html
List of UAs (Early 2012)
TIGER/Line shapefiles for UAs (Spring 2012)
Data SF1 Urban/Rural--“later in the year”
o Use of Tracts as Analysis Unit (Initial Phase)
o Reducing Jumps from 2.5 miles to 1.5o Use of a National Land Cover Data Baseo Changing Airport threshold from 10K to
2,500 enplanementso Eliminating the Central Place Concepto Establishing Minimum pop living
outside of group quarterso Splitting Large Areaso Naming Criteria
Proposed vs actual UA Criteria
Comments were due November 22, 2010
Splitting and Merging Large Areas
Some Questions for you
Are there any anticipated NEW Urbanized Areas? New MPOs
Any areas expected or reach or fall below 200,000 people? New TMAs
Any areas expected to fall below 50,000?
Is the MPO size threshold even an issue?

American Community Survey
Generally Familiar with it?
In 2005 the Long Form was replaced
• Continuous Survey Methodology• 250,000 Households sampled per month• About 1 in 40 Households sampled per yr• Response rates are lower than Long Form• Same transportation questions as 2000
Long Form
What is the ACS?
Place of WorkMeans of Transportation to Work
Carpool Occupancy to WorkDeparture Time for Work
Travel Time to WorkVehicles Available
Data Comes out Annually
Annual estimates(places over 65K pop)ACS1

DataFerrett is a unique data mining and extraction tool. It allows the
user to select a data basket full of variables and then recode those variables to create customize tables. DataFerrett helps locate and retrieve the data across the Internet regardless of where the data resides.

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.

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
24
Why are PUMAs Important?
NE Illinois (PUMAs)
PUMAs are a Tabulation Area for Annual ACS Data
● Represent 100K● Complete Coverage● Smaller than some
Counties● NO Swiss Cheese
25
How many PUMAs should this area have?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?- Starting Sept 2011
PUMA criteria
http://www.census.gov/geo/puma/puma2010.html
• Nest within states or equivalent entities
• Cover the entirety of the United States, Puerto Rico, Guam, and the U.S. Virgin Islands.
• Contain at least 100,000 persons
•Are built on counties and census tracts (PUMA delineations are subject to population thresholds and building block geography)
•Are contiguous

What should transportation agencies do?

States and MPOs just finished creating their custom geography (TAZs and TADs) to be used
for the 5-year data product
Who did TAZs? TADS?
How did the process go?
Where your TAZs returned for verification failures?

Number 8
A critical CTPP related research (NCHRP) study is just wrapping up
NCHRP 08-79 Producing Transportation Data Products from the American Community Survey that Comply with Disclosure Rules
• Cell Means and aggregates require 3 unweighted records
Some of the diclosure rules
• For Pt 3 Flow Tables:3 unweighted recordsfor each table, each cell, with the exception of the 1-way Means of Trans. table
• 3 unweighted records for the marginal's in any cross-tabulation with Means of Trans.
