The mean center of U.S. population is determined by the United States Census Bureau from the results of each census. Defined as the point at which an imaginary, flat, weightless, and rigid map of the United States would balance perfectly if weights of identical value were placed on it so that each weight represented the location of one person on the date of the census.

This is an overview or title slide to show all the points in your story routed on your map.
