U.S. Population Density

The United States population is of 333,287,557 persons. It includes the non-contiguous states of Alaska and Hawaii. It also includes the U.S. Territories of Puerto Rico and American Samoa.

The U.S. population is an estimate from 2022 obtained from USDA.

Population density is calculated by dividing the number of people by the area of each county.

The population density of the United States is 96 people per sq mi.

It is clear from the map that the most densely populated counties are metropolitan counties. These counties are mainly in coastal areas and lake regions.

Breaking the trend of coastal regions, you can see cities in Colorado, Texas, and even Oklahoma.

One of the interesting things about this map is that not only well known cities are darker, but other areas are dark as well.

For example the east corner of Texas is highly populated. This is El Paso Texas.

As you look through the map you can discover more and more cities you probably have heard of but were not aware they were so densely populated.

U.S. Population

Population density is affected by the size of the county. When you look at just population you find that they are not on the east coast but throughout the U.S.

As the map shows in yellow the least populated counties are in the Midwest.
