Montana population: a large, thinly settled state filling with newcomers

Montana had a population of 1,144,694 on July 1, 2025, the 9th smallest of the 50 states and DC, according to the Census Bureau's latest official estimates (Vintage 2025). Between July 2024 and July 2025 the population grew by 7,137 people (+0.63%), and the state now has 60,473 more residents than in April 2020 (+5.58%).1

West region, Mountain division

In 2025 the population was 81.8% white, 5.8% two or more races, 5.3% American Indian or Alaska Native and 5.2% Hispanic or Latino (all groups other than Hispanic are non-Hispanic).2 The median age is 41.0 years3, the median household income $77,0994 and the poverty rate 11.1%5.

The July 2025 estimate is the official current figure. The census is a count at one date; the estimates carry it forward with births, deaths and migration; the ACS is a survey weighted to the estimates, so its total is shown with a margin of error (±, 90% confidence) or controlled to the estimate.

Montana has few people for its size, and almost all of its growth since 2020 has come from Americans moving in from other states. Births no longer keep pace with deaths, very few residents were born abroad, and home values have climbed much faster than incomes.

Data as of October 29, 2026 (newest release used on this page).

Montana is among the most thinly settled states. Its 1.1 million1 residents share the 4th largest land area of any state, 145,550 square miles9, which works out to 7.9 people per square mile, the 3rd least densely populated state after Alaska and Wyoming10. This site covers states only, so figures for Helena, Bozeman or other towns are not included.

How many people live in Montana

The July 1, 2025 estimate of 1,144,694 is the highest ever recorded for Montana, which is larger than North Dakota, South Dakota and Wyoming; smaller than Idaho1. The estimates first passed one million in 2012 (1,005,47511), and the state has added people every year since 2000.

The largest one-year gain since 2000 came in the year to July 2021, when the estimate rose from 1,087,156 to 1,106,416. In all, Montana gained 60,473 people between April 2020 and July 2025, an increase of 5.58%. That rate was the 11th highest of any state, 2.5 percentage points above the US figure (3.10%), and higher than North Dakota, South Dakota and Wyoming; lower than Idaho. In the latest year, to July 2025, the population rose by 7,137, or 0.63%1.

Nearly half of Montanans live outside urban areas. The 2020 Census classed 46.6% of residents as rural, the 5th highest share in the nation and higher than every bordering state (Idaho, North Dakota, South Dakota and Wyoming). Nationally, the rural share was 20.0%13.

What percent of Montana is white

The answer depends on how race and Hispanic origin are counted:

  • White, not Hispanic (survey): 81.8% in 2025 (±0.3 percentage points), down from 83.3% in 20242. This is the figure in the summary at the top of the page.
  • White, not Hispanic (population estimates): 83.2% on July 1, 2025, the 5th highest share in the country and higher than every bordering state (Idaho, North Dakota, South Dakota and Wyoming). It was down from 84.6% in 2020.
  • White alone, any ethnicity: 87.1%, the 9th highest14.
  • White alone or in combination with another race: 91.0%15 in 2025.

On every definition the white share is far above the national one: the non-Hispanic white share from the survey is 26.8 percentage points above the US figure (55.0%)2. The diversity index, the chance that two residents picked at random belong to different racial or ethnic groups, is 32.2, making Montana the 5th least diverse state and less diverse than every bordering state (Idaho, North Dakota, South Dakota and Wyoming)17.

Hispanic or Latino residents of any race are 5.3% of the population, up from 4.2% in 2020 and lower than every bordering state (Idaho, North Dakota, South Dakota and Wyoming). Asian residents (alone) are 1.0% of the population, a share tied for lowest14 among the states. The largest Asian groups are Filipino (2,669 people) and Chinese, except Taiwanese (1,96618), both 2020–2024 estimates.

What percent of Montana is Black

Montana has the smallest Black population share of any state. Black residents (alone, of any ethnicity) were 0.7% of the population on July 1, 2025, the lowest in the nation, 12.8 percentage points below the US figure (13.5%). Wyoming and Idaho follow, both at 1.2%14.

The broader count, Black alone or in combination with another race, was 1.2% in the 2025 survey, again the lowest share (between 50th and 51st16 once margins of error are allowed for). The survey's non-Hispanic Black share was 0.6%, up from 0.3% in 20242.

Native Americans: the fifth-highest share

American Indian and Alaska Native residents make up a larger share of Montana than of all but four states. They were 6.4% of the population on July 1, 2025 (alone), the 5th highest share after Alaska, New Mexico, Oklahoma and South Dakota14. Counting people who are Native and another race, the share was 9.2% in 2025, 6.0 percentage points above the US figure (3.2%)19.

The 2020 Census recorded the tribes people named. The largest was the Blackfeet Tribe of the Blackfeet Indian Reservation of Montana, with 15,237 people alone or in combination, followed by the Crow Tribe of Montana (10,373), the Chippewa Cree Indians of the Rocky Boy's Reservation, Montana (6,144) and the Confederated Salish and Kootenai Tribes of the Flathead Nation (5,49320). People can report more than one tribe, so these counts overlap and should not be added up.

Growth since 2020: almost entirely people from other states

Of the three parts of population change (births minus deaths, moves between states, moves to and from abroad), only one has mattered much in Montana since 2020.

How Montana's population changed, April 2020 to July 2025
Births+58,554

Between April 2020 and June 2025, Montana gained 59,510 more residents from other states than it lost, the 13th highest net gain in the country and higher than North Dakota, South Dakota and Wyoming; lower than Idaho. That alone is close to the state's whole population gain over the period. Net international migration added 4,792, the 2nd lowest figure of any state, and natural change subtracted people: there were 58,554 births and 62,185 deaths, so births minus deaths came to −3,631. Montana is one of 20 states that recorded more deaths than births between April 2020 and June 20251.

The pull from other states peaked early. Net domestic migration was 20,693 in the year to June 2021, 15,474 in 2022, 9,017 in 2023 and 5,263 in 2024, before ticking up to 6,348 in the year to June 2025. Even at that lower level, Montana's gain relative to its size, 5.6 per 1,000 residents, was the 6th highest rate in the country, behind South Carolina, Idaho, North Carolina, Delaware and Tennessee. Domestic migration supplied 89%1 of the state's growth that year.

Source: Census Bureau, Population Estimates Program, Vintage 2025. Estimate years run from July 1 to June 30; the first covers April 1, 2020 to June 30, 2021.

The gap between deaths and births has narrowed: births minus deaths went from −1,781 in the year to June 2022 to −90 in the year to June 2025. The death rate, 10.0 per 1,000 residents, is higher than every bordering state (Idaho, North Dakota, South Dakota and Wyoming)1.

Where Montana's newcomers come from

Almost half of the people living in Montana were born in another state: 45.7% in 2025, 18.7 percentage points above the US figure (27.0%). Just over half, 50.4%, were born in Montana itself. Many came from nearby: 22.9% of residents were born elsewhere in the West, and 12.6%21 in the Midwest, both well above the national shares.

The Census Bureau's survey of individual moves for 2024 counted 35,735 people moving to Montana from other states and 34,901 leaving for one. California sent the most people, 4,872, a number not statistically different from the flow from Washington; Washington, Colorado and Arizona came next. The largest outflow went to Washington, 6,291, not statistically different from the flow to Arizona. The survey's net figure for the year, 834 (±6,64922), has a margin of error wider than the number itself, so it cannot settle whether more people arrived than left in that one year; the population estimates above, built from several sources, show a net gain.

Tax records also show a gain. On returns filed for 2022 and 2023, 5,332 more people moved to Montana than left, and the arriving households reported $500 million more income than the departing ones, a net income gain tied for 13th highest23 among the states.

Census counts since 1870, and the smallest House districts

Montana's first census count, in 1870, was 20,595. The population rose to 548,889 in 1920, then dipped to 537,60624 in 1930, the only fall between two censuses in the state's record. Today's population is 1.9 times1 the 1950 count.

Rank has barely moved: Montana was 44th of 5124 at the 1980 Census and still 44th of 51 in 2020. Between 2010 and 2020 its population grew 9.6%, 2.2 percentage points above the US figure (7.4%)6, and the 2020 apportionment gave the state 2 House seats, a change of +1. Each seat represents 542,704 people, the lowest in the nation; Delaware, at the other end, has 990,83725 people per seat.

Montana population by age: more retirees than children

Montana's median age is 41.0 years (±0.4 years), 1.5 years above the US figure (39.5 years); allowing for margins of error, it is between 9th and 17th3 oldest. The sharper change is in the balance between age groups. On July 1, 2025 Montana had 253,772 residents aged 65 and older and 231,653 under 18. In 2020 it was the other way round: 217,211 older residents and 234,19114 children.

Residents 65 and older are 22.2% of the population, the 8th highest share, 3.3 percentage points above the US figure (18.9%) and higher than every bordering state (Idaho, North Dakota, South Dakota and Wyoming). Children under 5 are 4.9%, down from 5.5% in 2020. Residents aged 18 to 64 make up only 57.6%, the 3rd lowest share of any state. As a result the dependency ratio, the number of children and older residents for every 100 people of working age, is 73.6, the 3rd highest14 in the nation.

Men slightly outnumber women: they are 50.2% of the population, a share that ranks tied for 6th highest14.

Incomes below the US, home values well above it

The median household income in Montana was $77,099 in 2025 (±$2,479), $7,681 (9%) below the US figure ($84,780) and lower than Idaho, North Dakota and South Dakota; not statistically different from Wyoming. Allowing for the survey's margins of error, Montana ranks between 33rd and 42nd4 from the top. Prices are lower than average: the Bureau of Economic Analysis puts Montana's overall price level at 94.6 for 2024 (US = 100), and its utilities at 72.3, the 4th least expensive in the country. On a different measure, the bureau's personal income per resident adjusted for those prices, Montana had $59,203 in 2024, against $59,19526 for the US as a whole.

Home values are the exception. The median value of an owner-occupied home was $427,500 in 2025, $56,400 (15%) above the US figure ($371,100) and more expensive than North Dakota, South Dakota and Wyoming; less expensive than Idaho27. In inflation-adjusted 2025 dollars, the median home was worth $216,937 in 2005 and $319,353 in 2019; over the same years the median household income went from $64,786 to $71,971, and it is $77,09928 now.

The official poverty rate was 11.1% (±0.8 percentage points), not statistically different from the US figure (11.8%). Child poverty, at 11.9%, was 2.9 percentage points below the US figure (14.8%)5. The Census Bureau's Supplemental Poverty Measure, which counts taxes, benefits and local housing costs, puts Montana at 9.5% on average for 2023 to 2025, 3.5 percentage points below the US figure (13.0%)33. Food assistance reaches fewer people than in most states: an average of 79,828 people received SNAP each month in fiscal 2025, 7.0% of the population, the 7th lowest34 share.

Few residents on congregation rolls

Montana's congregations counted only 34.8% of residents in the 2020 U.S. Religion Census, the 4th lowest share and lower than every bordering state (Idaho, North Dakota, South Dakota and Wyoming). That is not a shortage of churches: Montana has 16.3 per 10,000 residents, the 13th highest figure. Christian congregations counted 34.5%35.

The Catholic Church is the largest body (10.4% of residents), followed by non-denominational churches and The Church of Jesus Christ of Latter-day Saints, which counted 50,552 members, 4.7% of the population and the 7th highest35 share among the states. Congregations report these numbers themselves; a low rate is not a measure of belief (religion overview).

More residents without health insurance in 2025

The share of Montanans without health insurance rose to 10.9% in 2025 (±0.6 percentage points), up from 8.8% in 2024. That is 2.5 percentage points above the US figure (8.4%) and higher than every bordering state (Idaho, North Dakota, South Dakota and Wyoming); the state now ranks between 6th and 10th highest. Among children the rise was larger: 11.0% were uninsured, up from 7.7% in 202436.

The longer series shows how far the figure had come down: 18.5% of residents were uninsured in 2008 and 8.1%28 in 2016, and it stayed near that level until 2024. In administrative records, Medicaid and CHIP enrollment in Montana changed by −6.2% between June 2025 and June 2026, to 205,41437 people.

Life expectancy at birth was 77.3 years in 2022, 0.2 years below the US figure (77.5 years)38.

Veterans: the third-highest share

Montana has 78,530 veterans, 8.6% of civilian adults in 2025 (±0.5 percentage points). That is the 3rd highest share, after Alaska (9.7%) and Virginia (9.0%), though the margins of error place Montana between 2nd and 4th. It is higher than Idaho, North Dakota and South Dakota; not statistically different from Wyoming39.

Few immigrants, and roots in Germany, Ireland and Norway

Montana has one of the smallest immigrant populations in the country. In 2025, 32,036 residents were born abroad, 2.8% of the population and the 2nd lowest share after West Virginia. The share was up from 2.1% in 2024. Montana's immigrants come more often from Europe (21.8%, 12.3 percentage points above the US figure (9.5%)) and from Northern America, the Census region that includes Canada (13.9%), than immigrants nationally, and less often from Latin America (23.1%21).

New arrivals from abroad are also few. Net international migration was 412 in the year to June 2023, the lowest in the nation, and 8991 in the year to June 2025.

Only 4.0% of residents aged 5 and older speak a language other than English at home, the 2nd lowest share, and 0.9%41 speak English less than "very well". Spanish is the most common other language (15,285 speakers in 2020–2024), followed by German (6,65542).

Asked about ancestry in 2020–2024, Montanans most often named German (22.9%), Irish (13.5%) and English (13.1%). The Norwegian share, 7.5%, is the 4th highest43 of any state.

Households, schooling and work

Montana has 481,275 households, averaging 2.32 people, the 9th smallest45 size in the country. Married couples head 48.2% of households, 1.6 percentage points above the US figure (46.6%), and 8.2% are headed by single mothers, a share tied for 3rd lowest44. The marriage rate was 9.2 per 1,000 residents in 2024, the 5th highest46; marriages are counted where they take place, not where the couple lives.

Among adults 25 and older, 94.6% have at least a high school diploma, 4.0 percentage points above the US figure (90.6%). The share with a bachelor's degree or higher, 36.2%, is not statistically different from the US figure (37.4%) and higher than every bordering state (Idaho, North Dakota, South Dakota and Wyoming)47.

Unemployment averaged 3.3% in 2025, the 9th lowest rate, and stood at 3.1%48 in September 2026 (preliminary). Commutes are short: the average one-way trip to work took 20.0 minutes, 7.4 minutes below the US figure (27.4 minutes) and tied for 5th shortest49 among the states.
