How this area compares with national benchmarks.

Olathe city is a mid-size city in Kansas, with 143,720 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #4 of 740 ranked by population — larger than 99% of them. The median age here is 36.6 years against 39.1 nationally, a slightly younger profile than the country as a whole.

This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table.

A household on the local median income would put about 14% 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. 73.7% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners.
