St. Martins city, MO in context

How this area compares with national benchmarks.

St. Martins city is a small town in Missouri, with 1,195 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #349 of 1,082 ranked by population — larger than 67% of them. The median age here is 41.4 years against 39.1 nationally, a slightly older 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 St. Martins city earn a median of $78,125 a year, essentially level with the national figure of $78,538 and 41% above the $55,543 median for the 374 Missouri cities we cover. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table.
