Wyoming Population 2018

573,720

The state of Wyoming is located in the central northwestern sector of the USA. While it is the 10th largest in terms of surface area, it has the lowest recorded population of any state in the Union. It is also the second most sparsely populated. Wyoming's population in 2018 is estimated at 573,720, up slightly from the 2010 Census. It's currently enjoying a healthy growth rate of 1.13%, which ranks 15th among all 50 states.

The population of Wyoming in 2018 can only be estimated at present because the last official census in the country took place in 2010. It’s necessary, therefore, to take the official figures and attempt to project them forward to the present day.

The 2010 census revealed that there were 563,626 people in Wyoming and that meant an increase of over 14% on the numbers declared at the Census of 2000. An updated estimate of the state's population shows 573,720 residents in 2018. That means Wyoming ranks 50th in terms of population.

Wyoming Area and Pppulation Density

This is a very sparsely populated state, and with an average of just 5.85 people for every square mile, only one other state in the entire US -- Alaska -- can boast a less dense population.

As of 2005, almost 51% of Wyomingites lived in one of the 13 largest municipalities of the state. The largest city, Cheyenne, has a population of just 63,335, followed by Casper (60,285) and Laramie (32,158).

The most populated counties in the state of Wyoming are Laramie county and Natrona county with respective populations of 98,327 and 79,547.

Wyoming Population History

Although most of Wyoming was acquired as early as the Louisiana Purchase of 1803, organized government began with the establishment of Oregon, Nebraska, and Utah Territories (1848-54). Later the area was included in Idaho, Dakota, and Utah Territories until Wyoming Territory was established in 1868 with the present State boundaries. Wyoming was admitted as a State on July 10, 1890.

In 1850 and 1860 present-day Wyoming had only limited census coverage, as part of Utah and Nebraska Territories. In 1870 census coverage included the whole of Wyoming Territory.

Wyoming Population History

In 1870, the population of Wyoming stood at just 9,118 but significant increases were to follow for the latter half of that century. Just ten years later in 1880, a rise of over 100% had taken the figure to 20,789, and a further 200% increase saw the population in 1890 rise to 62,555.

From that point up until the present day, the overall growth percentage increases have slowed down, although generally speaking, the picture has been one of sustained, if unspectacular, growth. There was an anomaly in 1990, however, when the census of that year revealed a fall in numbers of 3.4% on those declared ten years earlier.

Further rises were to follow, however, and that has continued to the present day where the population of Wyoming in 2016 exceeds 580,000.

Wyoming Population Projections

The fact that there was a fall in the population of Wyoming as recently as 1990 makes it a little difficult to predict numbers moving forward. However, recent censuses have indicated a return to sustained, if modest growth and therefore, by the time of the next census in 2020, the population may exceed the next milestone of 600,000.

Wyoming is currently enjoying one of the highest growth rates in the country, in part fueled by natural gas jobs in the area and an unemployment rate well below the country's average. Its growth over the last few decades has been in largely rural counties where natural gas exploration has taken off.

Given its healthy economic environment, open space and high growth rate, its population is estimated to be close to 700,000 by 2025.
