Maps showing centers of population from 1790 to 1920 and centers of foreign-born population, negro population, and urban and rural population. Also shown are median lines and points, and the geographic centers of the states.
Census statistics date back to 1790 and reflect the growth and change of the United States. Past census reports contain some terms that today’s readers may consider obsolete and inappropriate. As part of our goal to be open and transparent with the public, we are improving access to all Census Bureau original publications and statistics, which serve as a guide to the nation's history.
