Williston, ND population, income and ZIP codes

Williston city is a small city in North Dakota, with 27,964 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #6 of 406 ranked by population — larger than 98% of them. The median age here is 31.9 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 Williston city earn a median of $84,309 a year, 7.3% above the national figure of $78,538 and 23% above the $68,472 median for the 51 North Dakota 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 8.7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Williston city is valued at $262,700, 13.4% below the national figure and 41% above the $185,700 peer median, while median gross rent runs $1,106 a month, 21.3% below the national figure, or roughly $13,272 across a full year. A household on the local median income would put about 15.7% 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 3.1×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 50.9% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
