Rexburg, ID population, income and ZIP codes

Rexburg city is a small city in Idaho, with 39,589 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #10 of 236 ranked by population — larger than 96% of them. The median age here is 21 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 Rexburg city earn a median of $50,359 a year, 35.9% below the national figure of $78,538 and 21% 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 35.5% 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 Rexburg city is valued at $384,000, 26.6% above the national figure and 41% above the $271,500 peer median, while median gross rent runs $959 a month, 31.8% below the national figure, or roughly $11,508 across a full year. A household on the local median income would put about 22.9% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 7.6×, against roughly 3.9× nationally, so buying is out of reach on local earnings alone and the ownership market leans on outside income, equity or dual high earners. 23.5% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

Home values sit at 7.6× median household income, far past the 3.9× national mark, so ownership costs here are set by something other than local wages — second homes, retirees with equity, or commuters earning elsewhere. A median age of 21 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.

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.
