Population density has been monitored for more than 200 years in the U.S. During this time, the number of people living in the U.S. per square mile has grown from 4.5 in 1790 to 87.4 in 2010.
The current population of the U.S. is 332 million (2020), and the country ranks 146th in population density (87 pop/mi2 or 34 pop/km2).
Approximately 65 percent of the U.S. population, or nearly 2 out of every 3 Americans, live in the red line, known as the “100 Mile Zone.”
