The Census Bureau will be releasing the update to the 2010 Census Summary File 1 that will include characteristics for urbanized areas on Thursday. Here's the announcement from the recent Tip Sheet: Summary File 1 Urban/Rural Update File - Adds urban and rural population and housing unit counts to the 2010 Census Summary File 1 released in 2011. The update provides detailed tables on age, sex, households, families, relationship to householder, housing units, detailed race and Hispanic origin groups and group quarters population for each of the nation's urbanized areas and urban clusters, and for the urban and rural portions of the United States, states, counties and places. (Scheduled for release Sept. 27.) Also for an update on the social and economic characteristics, in a conversation with ACS staff, I was told that the ACS data files will not include the new UA until the release of the 2012 ACS in Oct-Dec of 2013. We are not getting them in the 2011 ACS because ACS staff did not get the geographic boundary information in time.

CTPP Profiles Using ACS 2006-2010 and Census 2010 Published at AASHTO website!

by Liang Long

Hi, all FHWA and AASHTO have created CTPP profile sheets using ACS 2006-2010 and Census 2010 data. These profiles are released at AASHTO website: http://download.ctpp.transportation.org/profiles_2012/transport_profiles.ht… . The profiles are designed to give transportation planners a handy way to examine trends by including two time points. The profiles are available for the U.S. total; all states; all counties; and places with population 5,000 or more, based on 2010 Census counts. The transportation profile has the following tables: Table 1 Selected Characteristics; Total Persons, Persons in Households, Total Households, Average Household Size, Average Household Income, Average Number of Vehicles per Households, Percent of Persons in Poverty, Percent Minority, Percent of Persons 65 and Over, Percent of Persons Foreign Born. Table 2 Mode to Work; Total Workers at Place of Residence, Mode to Work at Place of Residence and at Place of Work and Table 3 Mean Travel Time by Mode to Work. Please use browser IE or Firefox for profiles downloading. The website is currently not working for Google Chrome because of some Java issue.

FW: U.S. Census Bureau Releases Documentation Supporting the 2011 American Community Survey (ACS) 1-Year Estimates

by Gemignani, Nancy

The 2011 ACS (1-year) file will be released next week. Below is some information on the table changes. For the transportation folks, one new table is Worker Population For Workplace Geography. Also, those of us who have had trouble calculating an unemployment rate from the very detailed table, B23001, will be very excited to see a new table, B23025. This table contains only the basic information needed to calculate the unemployment rate, without any gender or age detail to wade through. Remember this file will have data for geographies (state, county, place, MCD) of 65,000+ population.

What is the latest 3-year ACS CTPP tabulation, and where can I find it? The last one I had was 2006-08. I need to calculate commuting patterns between Detroit and its suburbs.

detailed age (block level) for population in quarters

by mkaminowitz＠baltometro.org

I have a request for detailed 2010 age data by block for the population in households (aka excluding group quarters). This data is available in SF1 and SF2 at the tract level but not block. It has to be blocks because I need to aggregate up to TAZ, and our TAZ's split tract and block group boundaries. Has anyone come across this data or found a way of estimating it? Group quarters also does not have detailed age groups so we can't just subtract. Mara Mara Kaminowitz, GISP GIS Analyst .........................................................................

Re: [CTPP] comparing Census 2000 with 2006-2010 ACS results on Journey to Work

OOPS! I sent out the incorrect URL. The url I sent first was the one the IT people send to me for checking!

Differences to remember: 1. The 2006-2010 ACS is the compilation of survey over 60 months, and not a "point in time" like the decennial census. 2. Because the ACS covers all 12 months of the year, areas with seasonal population shifts, e.g. snowbirds, summer homes, and universities are likely to see the more differences than in other locations and reflect both the change is time, as well as change in survey methods. 3.

SF1 API variable IDs

by Ennis, Samuel

So I'm once again befuddled by the way the API handles variable IDs. I'm trying to retrieve data from table PCT20: "Group quarters population by group quarters type" from SF1. However the SF1 does not seem to follow the same variable formatting as the ACS 5-Year (it doesn't seem to use the _001E / _001M suffixes). In the example queries, the table "P001: total population" is retrieved using the ID 'P0010001'. Based on this I would've guessed that the 0001 designates the variable within the table in the same way that _001E does. However using this same style suffix on PCT20 results in an error. Does anyone know how these IDs are constructed? I haven't been able to find a variable list for SF1 that corresponds to this one<http://www.census.gov/developers/data/2010acs5_variables.xml>. Thanks much, Sam Ennis
