[CTPP] Adjusted Census Data

(This message was posted by Linda Gage of our State Data Center in California to the State Data Center LISTSERV. It may be of interest to the MPOs and State DOTs and others on the CTPP listserv. Chuck Purvis, MTC) The University of California, Los Angeles has created an ftp site for the recently released adjusted 2000 census data for all states at: http://www.sscnet.ucla.edu/issr/da/Adjusted/adjust_web.html. The Census Bureau does not support the use of the Adjusted 2000 Census Data. "The numbers were released pursuant to the order of the United States Court of Appeals for the Ninth Circuit in Carter v. Department of Commerce, 307 F.3d 1084. These numbers are not official Census 2000 counts. These numbers are estimates of the population based on a statistical adjustment method, utilizing sampling and modeling, applied to the official Census 2000 figures. These estimates utilized the results of the Accuracy and Coverage Evaluation (A.C.E.), a sample survey intended to measure net over- and undercounts in the census results. The Census Bureau has determined that the A.C.E. estimates dramatically overstate the level of undercoverage in Census 2000, and that the adjusted Census 2000 data are, therefore, not better than the unadjusted data. Accordingly, the Department of Commerce deems that these estimates should not be used for any purpose that legally requires use of data from the decennial census and assumes no responsibility for the accuracy of the data for any purpose whatsoever. The Department, including the U.S. Census Bureau, will provide no assistance in the interpretation or use of these numbers."
