Troy, ID population, income and ZIP codes

Troy city is a very small community in Idaho, with 908 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #106 of 236 ranked by population — larger than 55% of them. The median age here is 44.7 years against 39.1 nationally, a slightly older 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 Troy city earn a median of $87,589 a year, 11.5% above the national figure of $78,538 and 37% above the $63,864 median for the 100 Idaho cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 2.6% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Troy city is valued at $270,800, 10.7% below the national figure and within a couple of points of the $271,500 peer median, while median gross rent runs $958 a month, 31.9% below the national figure, or roughly $11,496 across a full year. A household on the local median income would put about 13.1% 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 3.1×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 86.2% 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.

With 908 residents, a handful of survey responses moves every median on this page. Compare Troy city against its county rather than against national figures.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.
