Kootenai ZIP codes — Kootenai County, Idaho

Kootenai County is a mid-size city in Idaho, with 177,736 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 40.8 years against 39.1 nationally, a slightly older 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 Kootenai County earn a median of $77,034 a year, 1.9% below the national figure of $78,538. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 9.3% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Kootenai County is valued at $467,400, 54.1% above the national figure, while median gross rent runs $1,330 a month, 5.4% below the national figure, or roughly $15,960 across a full year. A household on the local median income would put about 20.7% 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 6.1×, 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. 72.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

Home values sit at 6.1× 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.

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.
