Demographic, Economic and Educational Statistics

Information about people and population trends

Dr. John Weeks, director of the International Population Center, defines demography as "the scientific study of human populations." This research often involves gathering data from various sources. Two of our most common sources are the U.S. Census Bureau's decennial census and the American Community Survey (ACS). Both datasets can be accessed using American FactFinder. The Census Bureau reports both enumerated and sample data in the decennial census, and reports sample data for the ACS.  Unfortunately, some rural areas in South Dakota are not listed in the ACS due to small populations. This means that people researching those areas may need to refer to the previous decennial census for data. The Census Bureau also produces the Statistical Abstract of the United States to provide a convenient reference.

Other sources of demographic data include the U.S. Commerce Department's Bureau of Economic Analysis (BEA), the U.S. Department of Health and Human Services Gateway to Data and Statistics and the U.S. Department of Labor's Bureau of Labor Statistics. For more specific data, we also may utilize similar state agencies, such as the South Dakota Department of Health.

We currently have information on categories such as income, poverty levels and trendspopulation distribution and trends and race and ethnicity. These are mostly at the state and county level, with some population information for selected cities and towns.
