North Liberty, IA population, income and ZIP codes

North Liberty city is a mid-size town in Iowa, with 20,782 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #26 of 1,026 ranked by population — larger than 97% of them. The median age here is 31.8 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 North Liberty city earn a median of $103,933 a year, 32.3% above the national figure of $78,538 and 53% above the $67,791 median for the 290 Iowa cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 4.4% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in North Liberty city is valued at $300,000, 1.1% below the national figure and 92% above the $156,300 peer median, while median gross rent runs $1,226 a month, 12.8% below the national figure, or roughly $14,712 across a full year. A household on the local median income would put about 14.2% 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 2.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 68.5% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
