ZIP 64166 in context

How this area compares with national benchmarks.

ZIP 64166 is a very small community in Clay County, Missouri, with 273 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #867 of 1,035 ranked by population — larger than 16% of them. The median age here is 56 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 64166 earn a median of $148,636 a year, 89.3% 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 7.7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 64166 is valued at $425,600, 40.3% above the national figure, while median gross rent runs not published a month. The home-price-to-income ratio works out to 2.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 100% 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.

A median age of 56 puts ZIP 64166 well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages. With 273 residents, a handful of survey responses moves every median on this page. Compare ZIP 64166 against its county rather than against national figures.

The Census withheld gross rent for ZIP 64166 because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.

Reading ZIP 64166 in context

How 64166 sits inside Clay County and Missouri.

ZIP 64166 is tabulated inside Clay County, Missouri, one of 18 ZIP areas the Census publishes for that county and 1,035 across Missouri. This is one of the smallest tabulated ZIP areas in the state, the kind of rural route where a single subdivision or farm cluster accounts for most addresses. 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 64166 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 64166 reports a median household income of $148,636, 54% above the $96,345 county median, and 145% above the $60,651 typical MO ZIP. Owner-occupied homes are valued at a median of $425,600, 50% above the county figure and 163% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at not published a month, which is why it reads higher than the advertised rent on a listing for the same unit.

Missouri charges 4.225% statewide, and local governments overlapping 64166 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 64166 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.
