Spanish Fork, UT population, income and ZIP codes

Spanish Fork city is a small city in Utah, with 43,632 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #22 of 334 ranked by population — larger than 93% of them. The median age here is 27.2 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 Spanish Fork city earn a median of $98,497 a year, 25.4% above the national figure of $78,538 and 7% above the $91,818 median for the 170 Utah cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 6.5% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Spanish Fork city is valued at $444,200, 46.4% above the national figure and within a couple of points of the $437,400 peer median, while median gross rent runs $1,417 a month, essentially level with the national figure, or roughly $17,004 across a full year. A household on the local median income would put about 17.3% 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 4.5×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 79.2% 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.

A median age of 27.2 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.
