Adjusted Census Data

The following files are the "adjusted data" for the 2000 Census for the State of California by county. The Census Bureau recently released these data for every State after the 9th Circuit Court of Appeals ruled in Carter v. U.S. Department of Commerce, 307 F3d. 1084 (2002) that the Freedom of Information Act required their release.

Even though these data are public, they were not published on the Census' web site. The Bureau instead set up a process by which any interested party can request the data from them. The Bureau released a disclaimer along with these data.

To make it a little easier for those that just can't wait to get their hands on this data set, we have made it available for download via the Statewide Database. We have posted only the California files on our web site. If you need files for other states, please visit the Institute for Social Science Research Data Archive.

These "adjusted data" were developed by the Census Bureau as part of the Operational Plan for Census 2000. For more information on Census 2000 Operations please visit here. You can find more information about how these data were created by reading the Census document Accuracy and Coverage Evaluation survey documentation from the Census site. This link provides detailed documentation for the A.C.E. Revision II.

If you use these data and you have some interesting findings, we would appreciate it if you would share them with us. Also, if you crunch data for California from this site that might be interesting to other users and you don't mind sharing them, please let us know so we can put them up in our report section.
