U.S. Census Bureau at a Glance

The Census Bureau is the federal government’s largest statistical agency. We are dedicated to providing current facts and figures about America’s people, places, and economy. Federal law protects the confidentiality of all the information the Census Bureau collects.

Our Mission

The Census Bureau's mission is to serve as the nation’s leading provider of quality data about its people and economy.

We honor privacy, protect confidentiality, share our expertise globally, and conduct our work openly.

We are guided on this mission by scientific objectivity, our strong and capable workforce, our devotion to research-based innovation, and our abiding commitment to our customers.


Thomas Jefferson directed the first census in 1790. As required by the U.S. Constitution, a census has been taken every 10 years thereafter. In 1840, the Census Act authorized the establishment of a centralized Census Office. In 1902, the Census Office became a permanent organization within the Department of Interior. A year later, it was renamed the Bureau of the Census and moved to the new Department of Commerce and Labor.

Our Statistical Programs


  • The Decennial Census is the once-a-decade population and housing count required by the U.S. Constitution. The Census Bureau counts all 50 states, the District of Columbia, Puerto Rico, and the Island Areas. The results of the decennial census determine the number of seats for each state in the U.S. House of Representatives and are used to draw congressional and state legislative districts and to distribute hundreds of billions of dollars in federal funds each year.
  • The Economic Census measures the nation’s economy every 5 years, providing vital statistics for virtually every industry and geographic area in the country.
  • The Census of Governments provides comprehensive data about the nearly 90,000 state and local governments in the nation every 5 years.

  • The American Community Survey (ACS) is an ongoing annual survey that shows what the U.S. population looks like and how it lives. The ACS helps communities decide where to target services and resources.
  • Demographic surveys measure income, poverty, education, health insurance coverage, housing quality, crime victimization, computer usage, and many other subjects.
  • Economic surveys are conducted monthly, quarterly, and annually. They cover selected sectors of the nation’s economy and supplement the Economic Census with more frequent information about the dynamic economy. These surveys yield more than 400 annual economic reports, including principal economic indicators.
  • Sponsored surveys are demographic and economic surveys that we conduct for other government agencies. They include the Current Population Survey, the National Health Interview Survey, and the National Survey of College Graduates.
  • The Small Business Pulse Survey provides detailed information on the effect of the COVID-19 pandemic on small businesses as well as their participation in federal programs such as the Paycheck Protection Program.
  • The Household Pulse Survey asks questions about how the COVID- 19 pandemic affected education, employment, food security, health, housing, Social Security benefits, household spending, consumer spending associated with stimulus payments, intention to receive the COVID-19 vaccine, and transportation.

Population Estimates and Projections

  • Every year, the Census Bureau publishes population estimates and demographic components of change, such as births, deaths, and migration. This data can be sorted by characteristics such as age, sex, and race, as well as by national, state, and county location.
  • The Census Bureau estimates population size and characteristics. Population projections are based on future demographic trends, including births, life expectancy, and migration patterns.

In addition, explore the population clock, economic indicators, topical data visualizations, and infographics.
