|Map 1: Depopulation Is Most Prevalent in the Center of the Country
A map of the United States depicts the rate of depopulation across America from 1970 to 2000. Counties that added population over the 30-year span are called "growing counties" (total 2,362 or 75 percent); counties that lost population at a relatively constant rate are called "declining counties" (total 547 or 17 percent); and counties that not only lost population but saw the rate of loss increase in the 1990s are called "accelerated declining counties" (total 232 or 8 percent). There are a total of 3,141 counties.
