Blaine ZIP codes — Blaine County, Idaho

Blaine County is a mid-size town in Idaho, with 24,579 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 45.5 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Blaine County earn a median of $84,470 a year, 7.6% above the national figure of $78,538. 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 7.4% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Blaine County is valued at $663,800, 118.8% above the national figure, while median gross rent runs $1,217 a month, 13.4% below the national figure, or roughly $14,604 across a full year. A household on the local median income would put about 17.3% 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 7.9×, against roughly 3.9× nationally, so buying is out of reach on local earnings alone and the ownership market leans on outside income, equity or dual high earners. 75.5% 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.

Home values sit at 7.9× median household income, far past the 3.9× national mark, so ownership costs here are set by something other than local wages — second homes, retirees with equity, or commuters earning elsewhere.

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.
