United States by Density 2019

What are the most densely populated states in the United States of America? Here is a list of the top ten states with the largest population density:

  1. District of Columbia (Population density: 11,665 people per square mile)
  2. New Jersey (Population density: 1,213 people per square mile)
  3. Rhode Island (Population density: 1,022 people per square mile)
  4. Puerto Rico (Population density: 900 people per square mile)
  5. Massachusetts (Population density: 890 people per square mile)
  6. Connecticut (Population density: 737 people per square mile)
  7. Maryland (Population density: 625 people per square mile)
  8. Delaware (Population density: 500 people per square mile)
  9. New York (Population density: 414 people per square mile)
  10. Florida (Population density: 404 people per square mile)

And what about the least densely populated states in the US? These are the top ten states with the smallest population density:

  1. Alaska (Population density: 1 people per square mile)
  2. Wyoming (Population density: 6 people per square mile)
  3. Montana (Population density: 7 people per square mile)
  4. North Dakota (Population density: 11 people per square mile)
  5. South Dakota (Population density: 12 people per square mile)
  6. New Mexico (Population density: 17 people per square mile)
  7. Idaho (Population density: 22 people per square mile)
  8. Nebraska (Population density: 25 people per square mile)
  9. Nevada (Population density: 28 people per square mile)
  10. Kansas (Population density: 36 people per square mile)

For those who enjoy wide open spaces, the United States offers plenty of options. The large states of Alaska, Wyoming, and Montana have the lowest population densities in the country, with Montana having 7p/mi² in a population of 1,062,330, Wyoming 6p/mi² with a population of just 573,720 (also the lowest population in the country), and Alaska topping them all with only 1p/mi² relative to its population of 738,068 and total area of 570,641mi².

In comparison to the other states, the District of Columbia covers a tiny area of just 61mi², yet it has a population of 703,608 which makes it by far the densest state of all at 11,535p/mi². New Jersey follows with a population density of 1,228p/mi², and Rhode Island is close behind at 1,027p/mi² – both are also among the smallest states.

Statistics show a range of population densities in the most highly populated states. California has a total population of 39,776,830, and a population density of 255p/mi², Texas has a population of 28,704,330 and its population density is a relatively low 110p/mi² (although this is due to it also being one of the largest states at 261,232mi²), while Florida's population of 21,312,211 has a population density of 397p/mi². These numbers likely reflect the fact that some states have particularly populous cities, which is likely to skew the statistics somewhat – for example, New York has a total population of 19,862,512 and a population density of 421p/mi², but New York City is also the most highly populated city in the United States.
