As required by the U.S. Constitution, the Census Bureau conducts a complete count of residents of the U.S. every ten years, ending in "0". Known as the Decennial Census, the primary purpose of this count is to determine the apportionment for representatives in Congress. The information that is compiled in the Census is obtained from questionnaires. Some basic information (e.g.: age, sex, race) was obtained from all residents (100% data), whereas other, more detailed questions (e.g.: income, education, employment status) were only asked of a portion of the population (sample data). Starting with the 2010 Census, sample data were no longer compiled from the Decennial Census but rather will be obtained through the annual American Community Survey (ACS).
Data.census.gov is the new platform from the Census Bureau. All data and digital content from the U.S. Census Bureau can now be access through this one site. This platform replaced American Factfinder 3/30/2020. It provides access to data about the United States, Puerto Rico and the Island Areas. It is an important source for population, housing, economic and geographic information. The data comes from several government-sponsored censuses and surveys.
Statistical Abstract data present here ranges from our most recent edition to the historical abstracts compiled throughout the decades. Some of the data were scanned as an effort to make historical abstract information available to the public. The display of data will continue as historical records become available.
