Iona, ID population, income and ZIP codes

Iona city is a small town in Idaho, with 2,882 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #55 of 236 ranked by population — larger than 77% of them. The median age here is 28.1 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Iona city earn a median of $83,750 a year, 6.6% above the national figure of $78,538 and 31% above the $63,864 median for the 100 Idaho cities we cover. 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 6.8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Iona city is valued at $364,400, 20.1% above the national figure and 34% above the $271,500 peer median, while median gross rent runs $1,284 a month, 8.7% below the national figure, or roughly $15,408 across a full year. A household on the local median income would put about 18.4% 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 4.4×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 92.1% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

A median age of 28.1 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.

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.
