The Least Populated State In The US

Out of the 50 states in the United States of America, which state is the least populated? The least populated state is Wyoming, which can be found in the northwestern United States. Wyoming’s population is slightly more than half of 1 million people, estimated at approximately 578,000 people in 2018. Thirty-one of the most populous cities in the United States each have a population greater than that of the state of Wyoming.

Let’s learn some more about the state of Wyoming compared to other states in the United States.

Brief History

Before it became part of the United States, Wyoming was home to many Native American groups. Tribes like the Shoshone, Arapaho, and Lakota lived in and around Wyoming. Different parts of Wyoming would be claimed by the Spanish Empire over the centuries until the land was ceded to the United States following the Mexican-American War. Wyoming would become a US territory after this, and it would stay a territory until the end of the 1800s. The Union Pacific Railroad brought many people to Cheyenne, and mining and logging was prevalent during this time. Yellowstone National Park became the first ever national park on the planet in 1872. In 1890, Wyoming was admitted to the United States as the 44th state in the union.

Geography And Demographics

In terms of geography, Wyoming is found where the Great Plains meets the Rocky Mountain region, and the state rests on top of a large plateau dotted with many smaller mountain ranges. The highest point in the state is Gannet Peak with an elevation of around 4270 m or 13,800 feet, while in the state’s northeast corner the lowest portion of the state can be found, sitting at around 952 m or 2125 feet in at the Belle Fourche River Valley. Grand Teton National Park is found within the state, and the Grand Teton peak is the second highest mountain. The Teton range itself runs around 80 km or 50 miles through the northwestern portion of the state. Notable rivers in Wyoming include the Snake River, the Big Horn River, the Yellowstone River, and the Green River.

The country has grown slowly over the past half-decade, mainly in tourist-oriented regions like the County of Teton which acts as the gateway to the Grand Tetons. In 2015 Wyoming’s unemployment rate was approximately 4%. The primary drivers of Wyoming’s economy are energy extraction, agriculture, and tourism. Tourism is a major driver of the state’s economy, with the tourism industry bringing in around $2 billion in revenue for the state, and millions of people visit Wyoming’s national parks every year.

Random Facts About Wyoming

Here are some random facts about Wyoming:

The word Wyoming comes from a Lenape word that translates roughly to “at/on the large plain”.

Wyoming was actually the first state to give women the right to vote, with its legislators passing the bill in 1869. It’s possible that the reason the vote passed was that legislators wanted to attract new settlers to the region and therefore they wanted the territory to look more modern. In addition, the state of Wyoming elected Nellie Tayloe Ross to be governor after the death of her husband, Governor William Bradford Ross. She has so far been Wyoming’s only female governor. The official motto of the state of Wyoming is “Equal Rights’, which was adopted in 1955.

The vast majority of Yellowstone lies within the state of Wyoming. Only a small portion of the park lies outside the state. An average of almost 4 million people visit the park every year. One of Yellowstone’s most famous sights is “Old Faithful”, a geyser that erupts every hour and a half, give or take a few minutes.

It is often said that the state of Wyoming has only two escalators, both found in the city of Casper.

The official mammal of Wyoming is the Bison. Bison are actually more dangerous to people than bears in the state, hurting more people every year at Yellowstone than bear attacks, which are very rare. Nonetheless, conservation efforts are important to the Bison’s future.

Many fossils and dinosaur bones have been found in Wyoming, and Wyoming is one of just a few states to have a state dinosaur, which is the Triceratops.

Even though Wyoming happens to be a landlocked state, there are 32 islands large enough to receive names in the state. Most of these islands are found within three bodies of water: Jackson Lake, Yellowstone Lake, and Green River.
