The 5 Smallest States in Population

When we turn to look at population, we get an entirely different look at the country. With the exception of Vermont, the states with the lowest population are among the largest in land area and they're all in the western half of the country.

A low population with a large amount of land means a very low population density (or people per square mile).

  1. Wyoming - 563,626 people
    • Ranks as the 10th largest in land area - 97,813 square miles (253,334 square kilometers)
    • Population density: 5.8 people per square mile
  2. Vermont - 625,741 people
    • Ranks as the 45th largest in land area - 9,614 square miles (24,900 square kilometers)
    • Population density: 65.1 people per square mile
  3. North Dakota - 672,591 
    • Ranks as the 19th largest in land area - 70,699 square miles (1,717,853 square kilometers)
    • Population density: 1.1 people per square mile
  4. Alaska - 710,231 
    • Ranks as the largest state in land area - 663,267 square miles (183,109 square kilometers)
    • Population density: 9.5 people per square mile
  1. South Dakota - 841,180 (ranks as 17th largest in land area)
    • Ranks as the 17th largest in land area - 77,116 square miles (199,729 square kilometers
    • Population density: 10.9 people per square mile
