The U.S. Census Bureau is the leading source of statistical information about the nation’s people. Subjects include groups such as children, veterans, and the foreign-born, and characteristics such as age, sex, race, Hispanic origin, migration, ancestry, and language use, as well as health, education, employment, income and poverty.
Federal, state, and local governments, along with businesses, universities, international organizations, and researchers, use the Census Bureau’s population statistics for funding allocations, to inform policy, and to aid in city planning. The public uses these statistics to learn more about their community, the United States, and the world.
Our population statistics come from decennial censuses, annual surveys such as the American Community Survey (ACS) and the Current Population Survey (CPS), and the periodic Survey of Income and Program Participation (SIPP). In addition, the Census Bureau produces Population Estimates and Population Projections.
Since 1950, the Census Bureau has performed international analytical work and assisted in the collection, processing, analysis, dissemination, and use of statistics with governments in over 100 countries. Population estimates and projections for all countries and areas of the world with a population of 5,000 or more are published in the International Data Base. Subnational data and maps are available for many countries.
