population densities of under 1,081 people per square mile One third of the U.S. population lives in low density block groups, or as much asof the total land area of the United States.

Using the 2014-2018 American Community Survey 5-year Estimates , all U.S. Census block groups were sorted by population density and then divided in thirds with each third having approximately equal population of about 107.5 million.

The chart above takes those same block groups, but looks back at their population from the previous 6 years of ACS 5-Year Estimates.
