For Global HIV/AIDS statistics, see the Joint United Nations Programme on HIV/AIDS (UNAIDS) webpage on HIV Data, including:

• Its most recent report, 2008 Report on the Global AIDS Epidemic
• Its most recent AIDS Epidemic Update (explores new findings and trends)
• Fact sheets on The Epidemic by Country

The World Health Organization (WHO) has a page of Data and Statistics. Be aware that many reports and data sets here are identical to those of UNAIDS linked above, as WHO is a co-sponsor of UNAIDS.

The U.S. Census Bureau has its own webpage of Global HIV/AIDS Surveillance and an HIV/AIDS Surveillance Database.

The University of California, San Francisco’s HIV InSite has a page on the epidemic by Counties and Regions. The basic data is drawn from the UNAIDS report linked above, but each page is also filled with links to reports, organizations, and other resources on that county or region.
