X-12-ARIMA Seasonal Adjustment Program

Announcement on Update to X-12-ARIMA Website

The X-12-ARIMA website has been redesigned - users can access the new website at the same location as the old site at:

http://www.census.gov/srd/www/x12a/

The revision brings the website up to date with the new look-and-feel standards for the Census Bureau, and adds new content of interest to researchers and users new to X-12-ARIMA.

Pages for programs such as Win X12, X-12-Graph and Genhol have been moved to separate parts of the website, at the following URLs:

http://www.census.gov/srd/www/winx12/
http://www.census.gov/srd/www/x12graph/
http://www.census.gov/srd/www/genhol/

Users trying to access these sites at their old locations will be referred to the new pages.

The PC and Unix versions of X-12-ARIMA can be found at their previous locations:

http://www.census.gov/srd/www/x12a/x12downv03_unix.html

The Seasonal Adjustment Papers site has also been updated, with separate pages for papers listed by authors and topics of interest:

http://www.census.gov/srd/www/sapaper/sapaperbyname.html
http://www.census.gov/srd/www/sapaper/sapaperbytopic.html
