UNAIDS: Key Population AtlasFormed in 1996, UNAIDS is consortium of six organizations headed by the United Nations. One of UNAIDS four key stated goals is "reducing vulnerability of individuals and communities to HIV/AIDS." On this website, UNAIDS provides data about the rates of people living with HIV around the world with a focus on Key Populations - those communities that UNAIDS have identified as especially vulnerable to HIV infection. The Key Populations examined in this online atlas include sex workers, intravenous drug users, and incarcerated individuals.
