High-quality analysis of population and economic data is vital for evidence-based decision making at all stages of a country’s development. Combining exceptional access to international data with the expertise of its staff, the U.S. Census Bureau conducts applied research on a range of demographic, economic, and health issues.

U.S. Census Bureau experts work on a diverse spectrum of ongoing and short-term projects, including: 

• Government consultations, training seminars, and modeling
• Analytical reports on topics such as HIV/AIDS and population aging

The International Database (IDB) is a series of estimates and projections that provide a consistent set of demographic indicators, including population size and growth, mortality, fertility, and net migration, for more than 200 countries and areas.  It is widely used by policymakers and researchers, and is often cited by global news sources, websites, and other reports on population trends.

The online HIV/AIDS Surveillance Data Base is an international compilation of HIV prevalence and incidence data resources from various sources for countries in Africa, Asia, Europe, Latin America and the Caribbean, and Oceania. The HIV/AIDS Surveillance Data Base is designed to provide users with information on HIV/AIDS and is helpful as both a reference tool and a resource for policy, research, and evaluation.

Thematic reports on critical topics such as HIV/AIDS and population aging are regularly developed and published by the Census Bureau. These projects are supported by U.S. and international agencies such as the U.S. Agency for International Development (USAID), the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR), U.S. National Institute on Aging (NIA), and the United Nations Population Fund (UNFPA).

The U.S. Census Bureau’s international area is actively engaged in contract work for sponsors. We leverage our expertise in international demographic and economic affairs to produce focused reports on sponsors’ individual areas of interest. Census Bureau experts engage in specialized research and consultancy projects tailored to data user and sponsor needs. 

The International Collection is among the very largest of its kind in North America. Statistical materials form countries around the world as well as "sub-collections" of UN materials, periodicals, and the general/reference resources compose the collection. Many of the materials are in the native languages of the country of origin. Special historical prizes within the collection include such items as the 1831 Census of England and Wales Enumeration Abstract, the 1890 Census of Portugal, volumes of the 1897 Census of Russia, and the 1899 Census of Cuba, materials that substantially pre-date the assembly of the International Collection.

The Census Bureau Library participates in the interlibrary loan program and therefore external users can borrow collection materials through another library.
