Williams ZIP codes — Williams County, North Dakota

Williams County is a small city in North Dakota, with 39,368 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 32.3 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 Williams County earn a median of $90,224 a year, 14.9% above the national figure of $78,538. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 8.8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Williams County is valued at $267,800, 11.7% below the national figure, while median gross rent runs $1,108 a month, 21.2% below the national figure, or roughly $13,296 across a full year. A household on the local median income would put about 14.7% 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×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 57.2% 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.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.
