Mountain Home, ID population, income and ZIP codes

Mountain Home city is a mid-size town in Idaho, with 16,265 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #16 of 236 ranked by population — larger than 93% of them. The median age here is 31.4 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in Mountain Home city earn a median of $58,486 a year, 25.5% below the national figure of $78,538 and 8% below the $63,864 median for the 100 Idaho cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 12.4% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Mountain Home city is valued at $270,700, 10.8% below the national figure and within a couple of points of the $271,500 peer median, while median gross rent runs $1,061 a month, 24.5% below the national figure, or roughly $12,732 across a full year. A household on the local median income would put about 21.8% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 4.6×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 66.4% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
