Island Park, ID population, income and ZIP codes

Island Park city is a very small community in Idaho, with 169 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #200 of 236 ranked by population — larger than 15% of them. The median age here is 67 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 Island Park city earn a median of $74,750 a year, 4.8% below the national figure of $78,538 and 17% 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 6.5% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Island Park city is valued at $284,500, 6.2% below the national figure and 5% above the $271,500 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 3.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 92.8% 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 67 puts Island Park city well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages. With 169 residents, a handful of survey responses moves every median on this page. Compare Island Park city against its county rather than against national figures.

The Census withheld gross rent for Island Park city because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.
