ZIP code 66030

ZIP 66030 is a small city in Johnson County, Kansas, with 25,964 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #23 of 704 ranked by population — larger than 96% of them. The median age here is 32.3 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 ZIP 66030 earn a median of $93,891 a year, 19.5% above 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 6.9% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 66030 is valued at $281,700, 7.2% below the national figure, while median gross rent runs $1,306 a month, 7.1% below the national figure, or roughly $15,672 across a full year. A household on the local median income would put about 16.7% 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. 69.7% 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.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.

This is a mid-sized suburban ZIP inside a county that is split across many delivery areas.

Kansas charges 6.5% statewide, and local governments overlapping 66030 may add county, city or special-district levies on top. We publish the state floor for this ZIP rather than guessing a combined figure, because ZIP boundaries and taxing-district boundaries were drawn for different purposes and do not line up.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 66030 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
