Data Tools and Apps


Census Bureau, Infographics and Visualizations

The Census Bureau is working to increase our use of visualization in making data available to the public, and this gallery is an early part of that effort. The first posted visualizations will pertain largely to historical population data, building on prior work done to portray historical changes in the growth and redistribution of the U.S. population. For later visualizations, the topics will expand beyond decennial census data to include the full breadth of Census Bureau data sets and subject areas, from household and family dynamics, to migration and geographic mobility, to economic indicators.(source: website)
