North Chicago, IL population, income and ZIP codes

North Chicago city is a small city in Illinois, with 30,772 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #62 of 1,462 ranked by population — larger than 95% of them. The median age here is 23.6 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 Chicago city earn a median of $56,815 a year, 27.7% below the national figure of $78,538 and 23% below the $74,244 median for the 698 Illinois 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 21.9% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in North Chicago city is valued at $147,800, 51.3% below the national figure and 17% below the $179,100 peer median, while median gross rent runs $1,392 a month, 1% below the national figure, or roughly $16,704 across a full year. A household on the local median income would put about 29.4% 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 2.6×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 33.3% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

A median age of 23.6 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.
