ZIP 66021 in context

How this area compares with national benchmarks.

ZIP 66021 is a small town in Johnson County, Kansas, with 2,792 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #188 of 704 ranked by population — larger than 73% of them. The median age here is 37.9 years against 39.1 nationally, a slightly younger profile than the country as a whole. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in ZIP 66021 earn a median of $84,375 a year, 7.4% above the national figure of $78,538. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 3.7% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in ZIP 66021 is valued at $232,000, 23.5% below the national figure, while median gross rent runs $1,213 a month, 13.7% below the national figure, or roughly $14,556 across a full year. A household on the local median income would put about 17.3% 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 2.7×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 86.2% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. 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.

Reading ZIP 66021 in context

How 66021 sits inside Johnson County and Kansas.

ZIP 66021 is tabulated inside Johnson County, Kansas, one of 32 ZIP areas the Census publishes for that county and 704 across Kansas. Population sits in the small-town band, typically one main street plus the addresses that feed into it. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 66021 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 66021 reports a median household income of $84,375, 23% below the $110,188 county median, and 27% above the $66,250 typical KS ZIP. Owner-occupied homes are valued at a median of $232,000, 39% below the county figure and 86% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,213 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

Kansas charges 6.5% statewide, and local governments overlapping 66021 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 66021 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.
