Uses of data on the Group Quarters population

by Elaine.Murakami＠dot.gov

To the transportation data community: Susan Schechter, Chief of the ACS Office at the Census Bureau has asked federal agencies for their input on uses of Group Quarters data. Please see her email below. Please send your material to me by July 9, so that I can compile it and submit by July 12. Elaine Murakami 206-220-4460 (in Seattle) -----Original Message----- Sent: Monday, June 28, 2010 9:00 AM Subject: Uses of data on the Group Quarters population As you may know, the Census Bureau asked the Committee on National Statistics to establish a panel to review the statistical methodology for measuring the group quarters (GQ) population in the ACS. The Panel on Measuring the Group Quarters Population in the American Community Survey is considering user needs for ACS data on the various components of the group quarters population and will recommend alternatives to the current sample design, weighting procedures, and other methodological features that can make the ACS group quarters data more useful for small-area data users (users of ACS 5-year period estimates that generally need and analyze data for small governmental jurisdictions, census tracts, and block groups). The panel would like to understand GQ data from the perspective of the data user and has requested information on the specific uses of GQ data and characteristics of the GQ population. We would appreciate you letting us know if your agency has specific uses of GQ data or know of other GQ data uses (whether from ACS or from other data sources). A brief description of these uses would be very helpful as well. Susan Schechter Chief, American Community Survey Office U.S. Census Bureau

Older decennial & other census data and boundary files

by Nathan Erlbaum

Recently on our State data center Affiliate Listserv, someone asked about 1980/1970 census data and the following link was posted as a possible resource National Historical GIS site (http://www.nhgis.org/). Very accessible for searching and downloading tract data going back to 1970 (and earlier, where it exists). This appears to be a very useful link for those who are looking for historical data....btw its free Nathan Erlbaum Associate Transportation Analyst New York State Department of Transportation Policy & Planning Division Office of Policy, Planning & Performance 50 Wolf Road, 6th Floor, (Ave F & 9th St.) Albany, New York 12232 Tel: (518) 457-2967 Fax: (518) 457-4944 Email: nerlbaum(a)dot.state.ny.us Web: www.nysdot.gov ***************************************** IMPORTANT: This e-mail message and any attachments contain information intended for the exclusive use of the individual(s) or entity to whom it is addressed and may contain information that is proprietary, privileged, confidential and/or exempt from disclosure under applicable law.

Urban Area webinar

by Ed Christopher

On Friday, June 11, 2010 FHWA and Census Bureau hosted a webinar where the Census Bureau discussed their plans for delineating Urban, Urbanized and Urban Cluster areas. The webinar was recorded and is available at http://fhwa.na3.acrobat.com/p32512114/ along with the slides which can be downloaded from the "materials to take home" pod. In a few weeks the recorded webinar will be moved to its permanent home at the AASHTO CTPP website (http://ctpp.transportation.org/pages/webinars.aspx) along with the slides and a FAQ that is being developed from the questions asked during the webinar. If you have any Urban Area related questions please feel free to post them to this list serve and we will try to answer them for everyone. Thanks to all those who participated in the webinar. -- Ed Christopher 708-283-3534 (V) 708-574-8131 (cell) FHWA RC-TST-PLN 4749 Lincoln Mall Drive, Suite 600 Matteson, IL 60443

Fwd: RE: ansi v fips

by Nathan Erlbaum

I thought that the information noted below would be of interest to those who follow this list serve and are interested in geographic referencing for use with census products Here is information from the Census Bureau's website on these codes: American National Standards Institute codes (ANSI codes) are a standardized set of numeric or alphabetic codes issued by the American National Standards Institute (ANSI) to ensure uniform identification of geographic entities through all federal government agencies. These standards replace the Federal Information Processing Standards (FIPS) codes previously issued by the National Institute of Standards and Technology (NIST). The entities covered include: states and statistically equivalent entities, counties and statistically equivalent entities, named populated and related location entities (such as, places and county subdivisions), and American Indian and Alaska Native areas. ANSI maintains an Internet World Wide Web site of ANSI codes and information<http://www.ansi.org/default.aspx> [cid:image001.gif@01CAF5CA.DECEE3A0] . ANSI publications include: INCITS 38:200x<http://www.census.gov/geo/www/ansi/statetables.html>, (Formerly FIPS 5-2) Codes for the Identification of the States, the District of Columbia, Puerto Rico, and the Insular Areas of the United States INCITS 31:200x<http://www.census.gov/geo/www/ansi/countylookup.html>, (Formerly FIPS 6-4) Codes for the Identification of Counties and Equivalent Entities of the United States, its Possessions, and Insular Areas INCITS 454:200x<http://www.census.gov/population/www/metroareas/metrodef.html>, (Formerly FIPS 8-6) Codes for the Identification of Metropolitan and Micropolitan Statistical Areas and Related Areas of the United States and Puerto Rico INCITS 455:200x<http://www.census.gov/geo/www/cd110th/main110th.html>, (Formerly FIPS 9-1) Codes for the Identification of Congressional Districts of the United States INCITS 446-2008<http://geonames.usgs.gov/domestic/index.html>, (Geographic Names Information System (GNIS)) Codes for Named Populated Places, Primary County Divisions, and Other Locational Entities of the United States, Puerto Rico, and the Outlying Areas.
