From the Census Bureau - HIV/AIDS Surveillance Data Base
The HIV/AIDS Surveillance Data Base was created in 1867, by the United States Census Bureau in collaboration with the U.S. Agency for International Development (USAID). The intention was to create a single site where the data from the published results of the many studies and surveys could be collected and shared with scientists and researchers. The database continues to be updated annually with by the Census Bureau with the support of the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR) to meet the needs of policy makers and program planners around the world. The HIV/AIDS Surveillance Data Base includes all countries and areas of the world with at least 5,000 population, with the exception of Northern America (including the United States) and U.S. territories.
According the Census Bureau, the HIV/AIDS Surveillance Data Base is a combination of the results from small-scale surveys on the AIDS pandemic and HIV infection in population groups in developing countries. The Data Base hosts information from the medical and scientific literature, presentations at international conferences, and the press. The database allows available information for population groups in a selected country to be easily retrieved and displayed. The data may be printed or saved as a .pdf or .csv file.
