Castle Point, MO population, income and ZIP codes

Castle Point CDP is a small town in Missouri, with 2,792 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #217 of 1,082 ranked by population — larger than 80% of them. The median age here is 26.9 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Castle Point CDP earn a median of $34,679 a year, 55.8% below the national figure of $78,538 and 38% below the $55,543 median for the 374 Missouri cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 37.3% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in Castle Point CDP is valued at $57,300, 81.1% below the national figure and 62% below the $152,400 peer median, while median gross rent runs $1,129 a month, 19.7% below the national figure, or roughly $13,548 across a full year. A household on the local median income would put about 39.1% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is a stretch on median earnings. The home-price-to-income ratio works out to 1.7×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 57.6% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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.

Castle Point CDP is the unusual combination of expensive to rent and cheap to buy: rent takes 39.1% of median income while homes cost only 1.7× it. Where that pattern shows up, the gap is normally down to down-payment and credit barriers rather than price. A median age of 26.9 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.

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.
