Monmouth city, OR in context

How this area compares with national benchmarks.

Monmouth city is a mid-size town in Oregon, with 11,176 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #56 of 426 ranked by population — larger than 87% of them. The median age here is 26.2 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 Monmouth city earn a median of $66,858 a year, 14.9% below the national figure of $78,538 and 10% below the $74,006 median for the 228 Oregon 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 15.6% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Monmouth city is valued at $380,500, 25.4% above the national figure and within a couple of points of the $377,700 peer median, while median gross rent runs $1,137 a month, 19.1% below the national figure, or roughly $13,644 across a full year. A household on the local median income would put about 20.4% 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 5.7×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 45.5% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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 26.2 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.
