Twin Falls ZIP codes — Twin Falls County, Idaho

Twin Falls County is a small city in Idaho, with 92,121 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 35.8 years against 39.1 nationally, a slightly younger profile than the country as a whole. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in Twin Falls County earn a median of $65,338 a year, 16.8% below the national figure of $78,538. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 10.7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Twin Falls County is valued at $292,700, 3.5% below the national figure, 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 18.6% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 4.5×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 69.6% 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.

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.
