Both towns on its borders with figures record more crime per resident. What’s more, a Safety Grade of A− follows from crimes Lake St. Louis’ police reported over the years 2023 to 2025: #8 of 172 graded towns in Missouri. Annual rates stand at 0.8 violent crime and 4.6 incidents of property crime for every thousand residents, next to 5.8 and 26.3 in the rest of Missouri.
Crimes reported to the FBI per 1,000 residents a year, 2023–2025. “Rest of MO” is every other Missouri city and town in the FBI’s tables; the U.S. figure is the FBI’s national estimate as published, averaged over the three years. The FBI publishes no national homicide or robbery rate in our data, so those compare with all U.S. cities and towns in its tables.

17 people died in crashes on Lake St. Louis’s roads in 2019–2023
Lake St. Louis had 13 fatal crashes in five years, in which 17 people died; 4 were pedestrians. Most of these deaths (14 of 17) were on an Interstate passing through, so they say more about through-traffic than about the town’s own streets.
That is 18.8 deaths per 100,000 residents a year, above the median for Missouri towns of 5,000–25,000 people (7.6, 123 towns).
Deaths are counted where the crash happened, not where the people lived: a highway through town adds through-traffic deaths, and residents’ own risk on roads elsewhere isn’t here. Town rates sit below state and U.S. rates because a third of fatal crashes happen outside any town. Road safety is described here and is not part of the Safety Grade.

What this data can and can’t tell you
- It’s reported crime. Only incidents reported to and recorded by police appear here. Many crimes are never reported to police.
- One number for all of Lake St. Louis. A town-wide rate doesn’t show where incidents happen, and that can differ a lot from one part of town to another.
- Visitors count too. Incidents involving people who work, shop or visit are counted against Lake St. Louis’ residents, which raises the per-resident rate.
- Whose population. Rates use the FBI’s population for the department (19,805 in 2025); our figure for Lake St. Louis is 19,129 (2025 Census estimate).
- Gaps are real gaps. A missing year means the department didn’t report a full year, not that nothing happened.
