Hello all, I am finding discrepancies between population densities that I'm calculating in ArcGIS using Census 2010 population data and the TIGER geography shapefiles (in my case for the county and state level), and population density numbers posted on Census websites. The discrepancy is from the square mileage calculation, in particular. Does anyone know if this is because water bodies are subtracted from the total square mileage for the density calculation (or if there is another reason for the discrepancy)?

Data on Disabled Populations

by Elizabeth Hassett

Hi all, I have not been able to find any data on disabled populations in either SF1 2010 or ACS 2009 5-year data, specifically at the block group and tract levels. Does anyone know if disabled data indeed has not been released within these geographies/datasets? If it has not, does anyone know a good alternative for disabled data? Thank you, Elizabeth Hassett Syracuse Metropolitan Transportation Council 100 Clinton Square 126 N.

Disability Data

by Elizabeth Hassett

Hi all, I have not been able to find any disability data at the tract-level, either from ACS 2009 5-year data or anything else; does anyone know if disability data is available at the tract-level, and if so, which data set it would be in? Thanks, Elizabeth Hassett Syracuse Metropolitan Transportation Council 100 Clinton Square 126 N.

If you are interested in CB Urban Areas delineation

by Mark Sattler

Our MPO policy committee took a position supporting the concept of the multiple urbanized areas within our region being agglomerated and were encouraged by the August 24, 2010 Federal Register notice indicating that the Census 2000 UAs (Dallas-Fort Worth-Arlington, Denton-Lewisville, and McKinney) would potentially be combined. Therefore, we are disappointed and a bit confused by the August 4-5 listserv statements indicating that new criteria may have since been developed. Our policy officials have seen these discussions and are asking us to respond. Can you let us know what is going on with regard to these criteria and perhaps provide the rationale behind keeping the urbanized areas from 2000 (when the other criteria indicate that they should be combined)? Thanks.

Urbanized Area release clarification

by Ed Christopher

We just got more clarification from Census Bureau geography staff on the Urban Area release dates. 1. The Census Bureau will announce the list of Urban Areas and their populations based on the 2010 Census in early 2012. 2. TIGER/Line shapefiles with boundaries for these areas will be available in Spring 2012. 3. 2010 Census data will be released later in the year in the Summary File 1 Urban/Rural Update. -- Ed Christopher 708-283-3534 (V) 708-574-8131 (cell) FHWA RC-TST-PLN 4749 Lincoln Mall Drive, Suite 600 Matteson, IL 60443

RE: [CTPP] If you are interested in CB Urban Areas delineation

by Don Cooper

I realize that the specific criteria will be published in the FR. However, do we know whether any non-population-density criteria were included in the final criteria? Other than the airports that were used the last time around.

The Federal Register notice has been working its way through all the required reviews at the agency and department level. We are anticipating publication in September. Meanwhile, urban area delineation based on these criteria is underway. We are on track for an announcement of urbanized areas and urban clusters in early 2012." Elaine

CTPP e-Learning launched

by Weinberger, Penelope

E-Learning Modules This tool is appropriate for anyone looking for more information on the Census Transportation Panning Products derived from American Community Survey data. Please share. Previous CTPP tabulations have been based on the decennial census, the American Community Survey (ACS)-based tables represent a significant shift and necessitates education concerning these changes. Many users are unfamiliar with details of the new CTPP data product. With the current CTPP release, it is AASHTO's desire to provide training for users of this data. To that end, we have developed a series of brief interactive modules to address various aspects of the new CTPP data products. Each module consists of a "Technical" and an "Executive" track, there is an introductory module that will typically play once, upon accessing the e-Learning for the first time. This introductory module will explain the differences between the two tracks and show system navigation. The following two subject modules are available by clicking the link below.
