In the last 110 years, the United States has become very urbanized: in 1900, 60.4% of the population was rural and 29.6% urban while in 1990, those numbers changed to 24.8% rural and 75.2% urban. New 2010 Census figures show that this trend has continued:
The U.S. population grew by 27 million over the decade, to 308 million. But growth was unevenly distributed. Metropolitan areas, defined as the collection of small cities and suburbs that surround an urban core with at least 50,000 people, accounted for most of the gain, growing 10.8% over the decade to 257.7 million people.
Rural areas, meanwhile, grew just 4.5% to 51 million. Many regions—from the Great Plains to the Mississippi Delta to rural New England—saw population declines. About 46% of rural counties lost population in the decade, including almost 60% of rural counties that aren’t adjacent to a metro area, according to an analysis of Census data by Kenneth Johnson, senior demographer at the Carsey Institute at the University of New Hampshire.
Based on these 2010 figures of 308 million US residents (though the population now is just over 311 million), that means 83.67% of the US lives in metropolitan areas. I still want to see the breakdown of urban areas: how much of the population now lives in suburbs (50.0% of Americans in 2000 compared to 30.3% percent in central cities – page 33 of this report) compared to cities. It is interesting to note that rural areas have still grown in population even as nearly half of rural counties lost population. Where exactly are the rural growth spots and are these exurbs that will soon become part of a metropolitan region or tourist spots?
(The rest of the article talks about how the population continues to grow more in the South and West. Read more about that here.)
