Unlike China and India, the U.S. population is predicted to persist in growing throughout the century with no expected decrease (annual population growth is about 0.9%). The Census Bureau forecasts a U.S. population of 417 million in 2060.

While some of the most significant U.S. states include historic centers of population and industry like New York, Pennsylvania, and Ohio, the bulk is now situated in the so-called Sunbelt. These southern and southwestern regions have been boasting economically and demographically since the 1960s (California, Texas, Florida).

As a result, nowadays, about 40% of the U.S. population lives in counties on the shore.
