Lewis ZIP codes — Lewis County, Idaho

Lewis County is a small town in Idaho, with 3,649 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 48.9 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in Lewis County earn a median of $49,643 a year, 36.8% 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 17.4% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Lewis County is valued at $202,400, 33.3% below the national figure, while median gross rent runs $708 a month, 49.6% below the national figure, or roughly $8,496 across a full year. A household on the local median income would put about 17.1% 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 4.1×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 74.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.

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.
