Marion ZIP codes — Marion County, Oregon

Marion County is a mid-size city in Oregon, with 346,532 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 37.2 years against 39.1 nationally, a slightly younger profile than the country as a whole. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in Marion County earn a median of $74,624 a year, 5% below the national figure of $78,538. 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 13.1% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Marion County is valued at $383,300, 26.3% above the national figure, while median gross rent runs $1,333 a month, 5.2% below the national figure, or roughly $15,996 across a full year. A household on the local median income would put about 21.4% 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 5.1×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 62.2% 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.

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.
