McLean ZIP codes — McLean County, Illinois

McLean County is a mid-size city in Illinois, with 170,882 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 34.2 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 McLean County earn a median of $78,329 a year, essentially level with 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 13% of residents here, above the 12.4% national rate.

The typical owner-occupied home in McLean County is valued at $198,300, 34.6% below the national figure, while median gross rent runs $992 a month, 29.4% below the national figure, or roughly $11,904 across a full year. A household on the local median income would put about 15.2% 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 2.5×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 65.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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.
