Lake St. Clair CDP, MO in context

How this area compares with national benchmarks.

Lake St. Clair CDP is a very small community in Missouri, with 670 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #455 of 1,082 ranked by population — larger than 58% of them. The median age here is 35.2 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 Lake St. Clair CDP earn a median of $80,392 a year, 2.4% above the national figure of $78,538 and 45% above the $55,543 median for the 374 Missouri cities we cover. 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 0% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Lake St. Clair CDP is valued at $219,300, 27.7% below the national figure and 44% above the $152,400 peer median, while median gross rent runs not published a month. 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. 92.1% 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. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

With 670 residents, a handful of survey responses moves every median on this page. Compare Lake St. Clair CDP against its county rather than against national figures.

The Census withheld gross rent for Lake St. Clair CDP 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.
