[CTPP] Flow data for areas smaller than 20,000

by Elaine.Murakami＠dot.gov

Someone from Massachusetts: Did you leave me a phone message? I did not get the correct phone number to return your call. The 2006-2008 CTPP does NOT have any places or towns with less than 20,000 population. The 20,000 population threshold is a rule established by the Census Bureau which limits the geographic units tabulated when 3 years of ACS are pulled together. The threshold for 1-year ACS tabulations is 65,000 population. After 5 years of accumulation, there is no geographic population threshold. Elaine Murakami FHWA Office of Planning 206-220-4460

[CTPP] Directions on importing Summary File 1 into MS Access

by Elaine.Murakami＠dot.gov

Would anyone like to volunteer to test out these directions and then report back to the CTPP listserv on how well it worked? http://www2.census.gov/census_2010/04-Summary_File_1/0HowToUseMSAccessWi thSummaryFile1.pdf Sometimes when I send an email, the link gets broken. The full link ends in "....pdf" In the meantime, I am testing out the data access system at the Missouri data extractor (Dexter/uexplore) to look at Summary File 1. It is pretty easy, so far. http://mcdc.missouri.edu/cgi-bin/uexplore?/pub/data/sf12010 on this page, select the FIRST LINE "Datasets.html" then I selected Colorado. I chose counties in Denver 08031 using the FILTER (first set of boxes) and selected "tracts" and then I selected Table H 12 and got a comma-delimited file, which I read into excel. You have to select BOTH the geography fields in the LEFT box as well as the table (variable) fields in the RIGHT box. If you forget to select the geography fields, you will get the table variables without any corresponding geography, which is not very useful. Ask me how I know. J Finally, I thought that when the Census released the Summary File 1 files on the ftp site that it meant the data would also be in AFF2, but apparently this is not true. There are "quick tables" in AFF2, and these may satisfy your needs, but it is not the full set. Elaine Murakami FHWA Office of Planning 206-220-4460

[CTPP] PUMA Criteria

by Ed Christopher

I just received this form some of Census Bureau sources. I have not read it yet but you can bet that I will be bugging the MPO and state DOTs to make sure that they hook up with their State Data Centers and get involved in the process. --------------------- The Census Bureau published final criteria for Public Use Microdata Areas (PUMAs) on July 5, 2011. The notice, "Final Public Use Microdata Area (PUMA) Criteria and Guidelines for the 2010 Census and the American Community Survey," is available on the Census Bureau's website at: http://www.census.gov/geo/puma/puma2010.html. Questions and requests for further information should be addressed to the Geographic Standards and Criteria Branch, Geography Division, Census Bureau via e-mail at <geo.puma(a)census.gov> or telephone at 301-763-3056. -- Ed Christopher FHWA Resource Center Planning Team 4749 Lincoln Mall Drive, Suite 600 Matteson, IL 60443 708-283-3534 (V) 708-574-8131 (C)
