Wyoming Population 2018
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 Montana 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.
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).
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.
