The U.S. population is unevenly distributed across the country.

While some populous U.S. states hold historic centers of settlements and manufacturers like New York, Pennsylvania, and Ohio, the majority have now resided in the so-called Sunbelt, the southern and southwestern regions that have been demographically and economically growing since the 1960s (California, Texas, and Florida).

Nowadays the most of the biggest U.S. counties are concentrated among the top ten states in terms of population (California – 40m, Texas – 29m, Florida – 21m, New York – 20m, Pennsylvania – 13m, Illinois – 13m, Ohio – 12m, Georgia – 11m, North Carolina – 10m).

The maps below clearly explain the uneven distribution of the population of the United States.

Reddit user Curious kid created a great map of the United States population deciles by latitude and longitude. Each colored region on the map contains one-tenth (30.8 million) of the total U.S. population.

But we can also try to divide the United States territory into 50 regions of an equal population separated by lines of longitude.
