Arco city, ID in context
How this area compares with national benchmarks.
Arco city is a very small community in Idaho, with 842 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #113 of 236 ranked by population — larger than 52% of them. The median age here is 37.1 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 Arco city earn a median of $31,023 a year, 60.5% below the national figure of $78,538 and 51% below 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 35.9% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.
The typical owner-occupied home in Arco city is valued at $157,700, 48% below the national figure and 42% below the $271,500 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 5.1×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 66% 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.
With 842 residents, a handful of survey responses moves every median on this page. Compare Arco city against its county rather than against national figures.
The Census withheld gross rent for Arco 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.
