Idaho City, ID population, income and ZIP codes

Idaho City city is a very small community in Idaho, with 556 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #140 of 236 ranked by population — larger than 40% of them. The median age here is 38.8 years against 39.1 nationally, a slightly younger profile than the country as a whole. 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 Idaho City city earn a median of $41,111 a year, 47.7% below the national figure of $78,538 and 36% below the $63,864 median for the 100 Idaho cities we cover. 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 5.6% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Idaho City city is valued at $94,500, 68.9% below the national figure and 65% below the $271,500 peer median, while median gross rent runs $776 a month, 44.8% below the national figure, or roughly $9,312 across a full year. A household on the local median income would put about 22.7% 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 2.3×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 66.3% 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.
