United States Population Density Map
The height of each state represents the population density while the volume of the figure represents the state's total population. To obtain the height, the population per square mile was multiplied by 1,000 to get the height in meters.
The Northeast US has many densely populated states, including New Jersey, the most dense of them all. The high yellow bar is the District of Columbia, but it does not qualify as a state.
Many people requested that I show smaller regions in states with large population disparities from region to region. Here, I compare the Chicago area with the rest of Illinois.
We see Southern California; Clark County, Nevada; and the Arizona Sun Corridor separated from the rest of their respective states.
Upstate and Downstate New York
Downstate New York far exceeds surrounding areas in population density.
