Cassia ZIP codes — Cassia County, Idaho

Cassia County is a small city in Idaho, with 25,165 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 33.1 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in Cassia County earn a median of $67,042 a year, 14.6% below the national figure of $78,538. 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 10.3% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Cassia County is valued at $257,300, 15.2% below the national figure, while median gross rent runs $920 a month, 34.6% below the national figure, or roughly $11,040 across a full year. A household on the local median income would put about 16.5% 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 3.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 70% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

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.
