Lee's Summit, MO population, income and ZIP codes

Lee's Summit city is a mid-size city in Missouri, with 102,583 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #6 of 1,082 ranked by population — larger than 99% of them. The median age here is 38.6 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 Lee's Summit city earn a median of $104,989 a year, 33.7% above the national figure of $78,538 and 89% above the $55,543 median for the 374 Missouri cities we cover. 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 5.5% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Lee's Summit city is valued at $313,200, 3.2% above the national figure and 106% above the $152,400 peer median, while median gross rent runs $1,382 a month, 1.7% below the national figure, or roughly $16,584 across a full year. A household on the local median income would put about 15.8% 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. 73.6% 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.
