Least populous state
Wyoming has the smallest population of any state, fewer than 600,000 residents.

Wyoming is the least populous state in the United States, with about 587,000 residents across 253,335 km² — the 10th-largest area in the country and the lowest population density of any state after Alaska, at roughly 2.3 people per km². Admitted in 1890, it was the first territory in the world to grant women the vote (1869), earning it the Equality State nickname, and it produced the first female governor in U.S. history, Nellie Tayloe Ross. Its economy is the most mineral-dependent in the nation: Wyoming is the top U.S. coal producer by a wide margin, a major producer of natural gas, crude oil, uranium and trona (soda ash), and it levies no individual or corporate income tax. Tourism is the second pillar, built on Yellowstone — the world's first national park — Grand Teton, Devils Tower and Jackson Hole. Teton County has the highest per-capita income of any county in the United States, while the state as a whole combines low unemployment, very low population density and high energy output per resident.
