Twin Falls city, ID in context

How this area compares with national benchmarks.

Twin Falls city is a small city in Idaho, with 53,219 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #8 of 236 ranked by population — larger than 97% of them. The median age here is 34.1 years against 39.1 nationally, a slightly younger profile than the country as a whole. 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 Twin Falls city earn a median of $60,760 a year, 22.6% below the national figure of $78,538 and 5% below the $63,864 median for the 100 Idaho cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 10.8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Twin Falls city is valued at $279,400, 7.9% below the national figure and 3% above the $271,500 peer median, while median gross rent runs $1,011 a month, 28.1% below the national figure, or roughly $12,132 across a full year. A household on the local median income would put about 20% 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. 63.3% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.
