Rock River, WY population, income and ZIP codes

Rock River town is a very small community in Wyoming, with 254 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #115 of 205 ranked by population — larger than 44% of them. The median age here is 29.7 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Rock River town earn a median of $62,750 a year, 20.1% below the national figure of $78,538 and 10% below the $69,912 median for the 54 Wyoming 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 21.7% 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 Rock River town is valued at $128,300, 57.7% below the national figure and 49% below the $251,500 peer median, while median gross rent runs $1,558 a month, 10.8% above the national figure, or roughly $18,696 across a full year. A household on the local median income would put about 29.8% 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 2×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 46.7% 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.

A median age of 29.7 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. With 254 residents, a handful of survey responses moves every median on this page. Compare Rock River town against its county rather than against national figures.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.
