United States Census Data: Home

A comprehensive guide to information produced by the Bureau of the Census


The Census Bureau is part of the Department of Commerce.  The Bureau gathers analyzes and disseminates a wide range of information about American communities and the people who live and work in them.  Richardson Library has an extensive collection of census documents and maps on-site, but there is far more information available online.  Use this guide to locate information about demography, economic indicators and more both in the library and on the internet.

Richardson Library is an affiliate of the Maryland State Data Center (SDC). The Maryland SDC provides access to extensive expert analysis, training, and extension of Census products. This significant support is provided by the network’s dedicated local professionals in their roles as economic developers, librarians, demographers, and research professionals.

2020 Census Results

The U.S. Census Bureau today released its 2020 Demographic Analysis, which provides a range of estimates — low, middle and high — for the nation’s population as of April 1, 2020. Instead of collecting responses from households like the 2020 Census, Demographic Analysis uses current and historical vital statistics records and other data to estimate the size of the U.S. population. By releasing these estimates ahead of the first results from the 2020 Census, Demographic Analysis offers an independent measure of the population for comparison with the official census counts.

Based on varying assumptions about the population, Demographic Analysis produced three different estimates for the size of the U.S. population on April 1, 2020:
