| 词条 | Median center of United States population |
| 释义 |
The median center of U.S. population is determined by the United States Census Bureau from the results of each census. The Bureau defines it to be: {{"|the point though which a north-south line and an east-west line each divides the total population of the country in half.[2]}}As of the 2010 U.S. census, this places roughly 154.4 million Americans living on each side of a longitude line passing through a location in Pike County, Indiana, and the same number living on each side of a latitude line through the same point. During the 20th century the median center of U.S. population moved roughly {{convert|180|miles|abbr=on|sigfig=3}} southwest, from a location in Randolph County, Indiana to a location in Daviess County, Indiana. The majority of this southwest shift happened in the second half of the century, as the center shifted within a narrow circular band between 1900 and 1950 – all within roughly {{convert|25|miles|abbr=on|sigfig=2}} of the 1900 starting point in Randolph County.
