The median household income in Lee’s Summit stands at $102,531, according to U.S. Census Bureau estimates. That figure runs above both of the counties the city straddles — Jackson County, at $68,577, and Cass County, at $87,535 — and above the Missouri statewide median of $70,702.
Lee’s Summit spans two counties, Jackson and Cass, which is why both appear here alongside the state as points of comparison. The city’s median runs above all three.
The number covers the full city and does not break out variation between Old Town and the newer subdivisions that make up most of Lee’s Summit’s land area. As a citywide figure, it is the backdrop against which local decisions — utility rates, stormwater assessments, school bond debt — get weighed.
These are 2020–2024 ACS 5-year estimates. Each figure carries a margin of error; the ladder above marks each ±MOE.
