Castleford, ID population, income and ZIP codes

Castleford city is a very small community in Idaho, with 166 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #203 of 236 ranked by population — larger than 14% of them. The median age here is 40.1 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 Castleford city earn a median of $44,167 a year, 43.8% below the national figure of $78,538 and 31% below the $63,864 median for the 100 Idaho cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 13.9% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Castleford city is valued at not published, while median gross rent runs $883 a month, 37.2% below the national figure, or roughly $10,596 across a full year. A household on the local median income would put about 24% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. 59.7% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

The Census withheld home value for Castleford 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.
