Siloam Springs, AR population, income and ZIP codes

Siloam Springs city is a mid-size town in Arkansas, with 18,096 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #26 of 625 ranked by population — larger than 95% of them. The median age here is 31 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 Siloam Springs city earn a median of $65,725 a year, 16.3% below the national figure of $78,538 and 33% above the $49,306 median for the 209 Arkansas 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 13.4% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Siloam Springs city is valued at $205,000, 32.4% below the national figure and 59% above the $128,900 peer median, while median gross rent runs $941 a month, 33.1% below the national figure, or roughly $11,292 across a full year. A household on the local median income would put about 17.2% 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 3.1×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 56.7% 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.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
