CENTER OF POPULATION: 1790 TO 1970 9 "Center of population" is that point which may be considered as the center of population gravity of the United States, or that point upon which the United States would balance if it were a rigid plane without weight and the population distributed thereon with each individual being assumed to have equal weight and to exert an influence on a central point proportional to his distance from that point] For dates of admissions of the States and changes in areal definition, see "State Origins and Boundaries," United States Summary, U.S. Census of Population: 1970.
