Center of Population Still in Missouri

The center of population is still in Missouri, the Census Bureau reports. The center's latitude and longitude place it 14.6 miles northeast of the tiny town of Hartville. The center has been ambling through Missouri since 1980. Every decade after completing the census, the Census Bureau calculates the mean center of population. It defines the mean center "as the place where an imaginary, flat, weightless and rigid map of the United States would balance perfectly if all residents were of identical weight." It's imaginary, but instructive. 

Between 2010 and 2020, the center of population moved only 11.8 miles. This is the shortest distance the center has moved since 1920 and the second shortest distance ever, the Census Bureau reports. It is also the most southerly move ever. "This southerly drift and shorter distance can be attributed to a strong pull on the center by continued population growth in the Southeast," the Census Bureau explains.

The Census Bureau also calculates the mean center of population for states and counties. You can see your state and county centers of population and how far they moved between 2010 and 2020 on this data visualization.
