Wyoming is the 10th largest state in the US by area and the smallest by population — with just 580,000 residents, it has fewer people than the city of Memphis, Tennessee. Most Americans know it as the home of Yellowstone and maybe a cowboy hat or two. But Wyoming's real story is far stranger, more complex, and more fascinating than the postcard version. Here are 10 things most people don't know.
1. Wyoming Has More Cows Than People — By a Lot
Wyoming has approximately 1.3 million cattle versus roughly 580,000 humans. The cattle-to-human ratio of more than 2:1 makes Wyoming one of only a handful of US states where cows literally outnumber people. Ranching is not a romantic notion here — it is the backbone of significant portions of the state's economy and cultural identity.
2. Wyoming Was the First US State to Grant Women the Right to Vote
In 1869 — a full 51 years before the 19th Amendment extended voting rights to women nationally — the Wyoming Territory became the first government in the world to grant women full voting rights in general elections. Wyoming's motto, "The Equality State," is a direct reference to this. Women also served on Wyoming juries and held elected office in Wyoming decades before anywhere else in the country. This progressive first coexisting with Wyoming's deeply conservative contemporary politics is one of the state's most fascinating contradictions.
3. Jackson Hole Is One of the Most Expensive ZIP Codes in America
Jackson, Wyoming (ZIP code 83001) regularly appears in the top 10 most expensive ZIP codes in the entire United States — in a state with a total population barely larger than a mid-sized city. Median home prices in Jackson Hole far exceed $2 million, driven by billionaire buyers (Dell, Bezos, and numerous hedge fund personalities own property there), the presence of world-class skiing at Jackson Hole Mountain Resort and Snow King, spectacular Grand Teton views, and zero Wyoming state income tax (the same attraction as Florida).
4. Yellowstone Sits Atop One of the World's Three Active Supervolcanoes
Yellowstone National Park — which sits almost entirely within Wyoming — is underlain by a supervolcano, one of only three confirmed active supervolcanoes on Earth (the others are in Indonesia and New Zealand). The Yellowstone caldera is roughly 34 by 45 miles and the magma chamber beneath it is one of the largest in the world. The last supereruption, approximately 640,000 years ago, deposited ash across more than half of North America. The USGS monitors Yellowstone continuously — it is the world's most instrumented volcanic system. The probability of a supereruption in any given year is approximately 0.00014%, but the consequences if it occurred would be civilizational in scale.
5. Wyoming Has No Corporate or Personal Income Tax — and Is a Tax Haven
Wyoming has no personal income tax, no corporate income tax, no inheritance tax, and no gift tax. This makes it one of the most tax-friendly states in the country and has turned it into a significant offshore-like jurisdiction for trusts, LLCs, and corporations. Wyoming pioneered the LLC structure in the US in 1977 (the Wyoming LLC Act) and remains a preferred state for business formation. Thousands of businesses incorporate in Wyoming purely for tax and liability structuring purposes without any actual operations in the state.
6. Half of Wyoming's Land Is Owned by the Federal Government
Approximately 48% of Wyoming's total land area is owned or managed by the federal government — including national parks (Yellowstone, Grand Teton), national forests, Bureau of Land Management lands, and military installations. This creates permanent, unresolvable tension between the state's conservative/libertarian political culture (which strongly opposes federal land control) and the environmental and tourism economy that federal protection enables. Wyoming's two largest industries — tourism and energy extraction — are both fundamentally dependent on federal land management, and yet Wyoming political culture is broadly hostile to federal authority. It's a paradox the state has never fully resolved.
7. Wyoming Is the Energy Powerhouse of the West
Despite its tiny population, Wyoming is a massive energy producer:
- It is the largest coal-producing state in the US, with the Powder River Basin in northeastern Wyoming accounting for about 40% of all US coal production.
- Wyoming is a significant oil and natural gas producer.
- The state is also a major producer of trona (used to make soda ash/baking soda) — Green River, WY holds the world's largest deposit.
- Wyoming is increasingly a wind energy leader — its wide-open prairies and consistent winds make it one of the best wind energy sites in the US, and new transmission development is underway.
8. Wyoming Has the Lowest Population Density in the Lower 48
Wyoming's population density is approximately 6 people per square mile — less than any other contiguous US state (Alaska is less dense but is a special case). To put this in perspective, the entire population of Wyoming could fit into one medium-sized sports stadium. Driving through large swaths of Wyoming, you can travel an hour or more without seeing another vehicle. For many people, this is the entire appeal.
9. The Oregon Trail Ran Right Through Wyoming
The most important overland migration route in American history — the Oregon Trail — crossed Wyoming for hundreds of miles, and the evidence is still physically visible. Near Guernsey, Wyoming, the ruts carved by thousands of wagon wheels are still 5 feet deep in the soft sandstone. At Independence Rock, you can still read the names carved by emigrants in the 1840s. Wyoming was the crucible of westward expansion, and the state's landscape bears its scars in the most literal sense.
10. Wyoming Has No Major League Sports Teams — and Doesn't Want Them
Wyoming has no NFL, NBA, MLB, or NHL team — not even a minor league affiliate of significance. The biggest sporting events in the state are rodeo (the Cheyenne Frontier Days Rodeo is the largest outdoor rodeo in the world) and University of Wyoming Cowboys football. Residents seem remarkably unbothered by this. When your backyard offers elk hunting, fly fishing the Snake River, skiing Grand Targhee, and camping in the Wind River Range, the appeal of stadium sports is perhaps diminished.
