New 2004 ACS Tables by Workplace Geography

by Shimon Israel

Hi Everyone, On January 26th, the Census Bureau published new 2004 American Community Survey (ACS) means of transportation tables, by workplace geography. Means tables by workplace geography are only currently available for the 2004 ACS, and only for geographic summary levels with 250k+ in population. Additionally, group quarters information is excluded. Data for 2005 and beyond (appropriations-dependent) will be published for areas with 65k+ population (including PUMAs) on a yearly basis. Areas between 20-65k will be released with 3-year-averaged data, and areas <20k population (including census tracts and block groups) with 5-year-averaged data. ACS group quarters data collection for the U.S. and Puerto Rico began in January 2006. New tables for 2004 can be accessed from the ACS page on the Bureau's American Factfinder website: http://factfinder.census.gov/servlet/DatasetMainPageServlet?_program=ACS&_l… 2004 ACS tables on the means of transportation to work by workplace geography: o Sex of Workers by Means of Transportation for Workplace Geography o Sex of Workers by Travel Time to Work for Workplace Geography o Means of Transportation to Work by Age for Workplace Geography o Median Age by Means of Transportation to Work for Workplace Geography o Means of Transportation to Work for Workplace Geography (White Alone) o Means of Transportation to Work for Workplace Geography (Black or African American Alone) o Means of Transportation to Work for Workplace Geography (American Indian and Alaska Native Alone) o Means of Transportation to Work for Workplace Geography (Asian Alone) o Means of Transportation to Work for Workplace Geography (Native Hawaiian and Other Pacific Islander Alone) o Means of Transportation to Work for Workplace Geography (Some Other Race Alone) o Means of Transportation to Work for Workplace Geography (Two or More Races) o Means of Transportation to Work for Workplace Geography (White Alone, Not Hispanic or Latino) o Means of Transportation to Work for Workplace Geography (Hispanic or Latino) o Means of Transportation to Work by Citizenship Status for Workplace Geography o Means of Transportation to Work by Language Spoken at Home and Ability to Speak English for Workplace Geography o Means of Transportation to Work by Marital Status for Workplace Geography o Means of Transportation to Work by Educational Attainment for Workplace Geography o Means of Transportation to Work by Workers' Earnings in the Past 12 Months for Workplace Geography o Median Earnings in the Past 12 Months by Means of Transportation to Work for Workplace Geography o Means of Transportation to Work by Poverty Status in the Past 12 Months for Workplace Geography o Means of Transportation to Work by Occupation for Workplace Geography o Means of Transportation to Work by Industry for Workplace Geography o Means of Transportation to Work by Class of Worker for Workplace Geography o Means of Transportation to Work by Time Arriving at Work from Home for Workplace Geography o Means of Transportation to Work by Travel Time to Work for Workplace Geography o Aggregate Travel Time to Work (in Minutes) of Workers by Means of Transportation to Work for Workplace Geography o Means of Transportation to Work by Tenure for Workplace Geography o Means of Transportation to Work by Household Type for Workplace Geography o Means of Transportation to Work by Vehicles Available for Workplace Geography Please note that the Census Bureau plans to update and improve ACS data products for 2005.

New report on (Bay Area) disability trends, based on the American Community Survey

by Chuck Purvis

TO: CTPP-News Listserv This item may be of interest to transportation planners interested in disability statistics from Census 2000 compared to the American Community Survey. The bottom line is that if you are interested in disability statistics, stick with data from the 2003-to-current ACS. The working paper also suggests other national databases that might provide useful information on national/statewide/metro area disability statistics. The Metropolitan Transportation Commission has just released a report entitled "Disability in the San Francisco Bay Area: Comparing Data Between Census 2000 and the American Community Survey 2000-2004." The working paper is available here: http://www.mtc.ca.gov/maps_and_data/datamart/census/Disability_BayArea_Work… The main MTC Census page is here: http://www.mtc.ca.gov/maps_and_data/datamart/census/ MTC and ABAG staff will be working on a re-design of the Bay Area Census web site (http://www.bayareacensus.ca.gov/), to have page or pages devoted to American Community Survey analysis and issues. This is the very first in a long series of possible working papers and data summaries to be based on data from the US Census Bureau's American Community Survey. The abstract from this working paper discusses the purpose and intent of the study: As a characteristic of the general population, disability rates determined by the U.S. Census should not vary much year to year or survey to survey. This paper examines disability data from Census 2000 and the American Community Survey (ACS), years 2000-2004, for the 5 San Francisco Bay Area primary metropolitan statistical areas (PMSA). For most of the PMSAs, statistically significant differences exist between Census 2000 and ACS disability data, particularly for the go-outside-home and employment disability items. Differences in sampling technique, sampling instruments, and information reporting between Census 2000 and ACS data that might account for this variation are discussed. Census 2000 data shows 1.1 million disabled persons (any type of disability) residing in the ninecounty Bay Area. This is 17.6 percent of the Bay Area's population (age 5+). This compares to the 2000 American Community Survey that shows 0.8 million disabled persons (13.1 percent) in the Bay Area. ************************************************************** Charles L.
