Center of Population and Territorial Expansion, 1790 to 2010
Project #23 on iSENSEProject.org
Description
This data set from the U.S. Census Bureau shows the mean center of population: the place where an imaginary, flat, weightless, and rigid map of the United States would balance perfectly if all residents were of equal weight. Since 1790, the center of population has moved steadily westward, angling to the southwest in recent decades.SOURCE: Geography Division, "Centers of Population Computation for the United States 1950-2010," issued March 2011, available at http://www.census.gov/geo/www/2010census/centerpop2010/COP2010_documentation.pdf.
