Montana Population 2018


As of 2018, the estimated population of Montana is 1.06 million. Montana is a vast area of open space, situated in the northwest portion of the United States. It may be the fourth biggest state in the country in terms of sheer size, but its population statistics are a testament to the geography of Montana, most of which is not suitable for large development.

There are only two states in the US that are more sparsely populated than the aptly nicknamed Big Sky Country -- Alaska and Wyoming. In terms of pure population numbers, the state surpassed the 1 million mark according to estimates from the US Census Bureau for 2016. The estimated 2018 population is 1.06 million, making Montana the 44th most populous state. The state has reflected a moderate growth rate of 0.79%, which ranks 26th in the nation.

The US Census of 2010 confirmed that 989,415 people were living in Montana, an increase of 9.7% from the findings of 2000. The Montana population surpassed 1 million for the first time in 2012, and it now stands at 1.03 million.

With a sprawling land mass of 145,552.43 square miles, there are only three bigger states in the US. However, for every square mile of land, there is an average of just 6.86 people (2.65 per square kilometer) and that makes Montana the 48th most densely populated area in the country. Mountain ranges, lakes and national parks all contribute to that figure in a huge area of outstanding natural beauty.

There are few large urban areas in the state of Montana. The largest city is Billings, home to 110,263 people in 2016. Other sizable cities are Missoula (pop: 71,022) and Great Falls (pop: 59,638). Urban areas in Montana are actually growing quite rapidly, while more rural areas are gradually becoming less populated. This is a trend that is common among many states in the country.

Montana Demographics

94.8% of Montana's population speaks English, although there are many other languages spoken in the state, including Blackfoot, Assiniboine, Cheyenne, Plains Cree, Crow, Dakota and Kutenai. This is because Montana has one of the highest Native American populations in the US, with about 66,000 people of Native American heritage. This is the result of many treaties and federal legislation, including one that recognizes the Little Shell Chippewa, a nation of "landless" people in Great Falls recognized by the state but not the federal government. About 63% of these people live off reservation -- mostly in cities -- with Great Falls having the largest concentration of urban Indians.

Montana Population History

The eastern and central parts of Montana were acquired as early as the Louisiana Purchase of 1803, but had no organized government until Nebraska Territory was established in 1854. The northwestern part of Montana was included in the newly established Oregon Territory in 1848. The whole of the present-day State was included in Idaho Territory in 1863, and was established as a separate territory in 1864 with essentially its present boundaries. Montana was admitted as a State on November 8, 1889.

In 1860 census coverage of present-day Montana was limited to two forts enumerated in Nebraska Territory and some settlers in the Bitter Root Valley enumerated in Washington Territory. In 1870 census coverage included all of the present State.

Montana Population History

The first census in Montana was held in 1870, just after Montana was formally made a US State Territory (previously it had been a part of Oregon, Washington, Idaho and Dakota territories.) It recorded a population of 20,595. This was relatively small compared to other areas of the country, as the population explosion of the 1800s was slow to reach Montana.

However, increased migration helped to swell those numbers through the end of the 19th century. Just ten years later, in 1880, numbers of just over 20,000 had grown by just over 90% to 39,159 but the biggest spike in the history of Montana’s population was yet to come. The survey of 1890, held just after Montana became a full US state, showed an impressive increase of 265% that took the number of residents to 142,924.

Further increases followed but they began to slow down in the 1900s. In fact, the 1930 Census revealed a fall of just over 2% from the numbers declared ten years earlier. That ‘blip’ aside, steady growth dominated to the point where the population of Montana in 2016 has surpassed the 1 million mark.

Montana Population Growth

Montana's population growth has mainly been concentrated in its seven largest counties, with the heaviest growth in Gallatin County, while the city of Kalispell has seen a growth of over 40% in the last decade. This is expected to continue, as Montana's rural areas will continue to lose people while the urban areas grow.

Montana has a moderate population growth of 0.79%, which is about middle-of-the-road in the United States. Forecasts show Montana's population will grow 14% over the next 30 years, reaching 1.16 million by 2030.

It's also estimated that by 2030, Montana will be one of ten states in the country to have more people over the age of 65 than under the age of 18, and it will be one of only six states to have 25% of its population aged 65 and older, which could impact future growth.
