Public schools only, from the NCES Common Core of Data, placed by ZIP code — which schools are in this place, not which one a particular address is zoned for. A dash in a proficiency column is a gap in the federal file, not a bad result. Proficiency is measured against Missouri’s own standard, so it is ranked within state. How to read school figures.

People moving in and out

Based on the address on federal tax returns, compared with the same filers a year earlier. It counts people who file, and sees a move only when the address on a return changes. Domestic moves only: people arriving from abroad are left out. This is the figure for St. Charles County, MO. IRS Statistics of Income, filing years 2022–2023.

The hazards accounting for most of this area's expected annual loss are inland flooding, tornado and earthquake, with inland flooding alone responsible for 54% of it.

Hazard ratings are AreaProfile calculations derived from the FEMA National Risk Index v1.20.0 (December 2025). FEMA publishes at county level. City values are the population-weighted mean of the counties the city overlaps, using AreaProfile place-to-county land-area weights. FEMA does not endorse this presentation. Higher physical resilience means lower exposure.

Below these are deaths rather than offenses, published for the county. The two measure different things and are not comparable with each other.

Wentzville's police department reported 139 violent offenses per 100,000 residents, near the middle of places with a department reporting. Property crime runs at 741.

St. Charles County has a modeled homicide rate of about 2.1 per 100,000 residents a year, because the CDC suppresses counts this small, lower than most counties measured. The CDC does not publish this below county level.

Firearm deaths of all intents run at 10.6 per 100,000 — more than the homicide rate, since the figure counts suicides and accidents as well as homicides.

Drug overdose deaths run at 12.7 per 100,000 residents in St. Charles County.

Firearm deaths count every intent together, and nationally the majority are suicides rather than homicides, so the firearm figure and the homicide figure above it count some of the same deaths twice over. They overlap and should not be added together.

Offenses are reported to the FBI by Wentzville’s own police department and shown only where it reported every month of the year; a partial year is withheld rather than scaled up. Reported crime is what police recorded, which is not the same as what happened. Death rates are crude rates — deaths divided by population, not adjusted for age — except where a count was too small for the CDC to publish and it modeled the rate, which the card marks. They come from provisional death certificate records, published by the CDC by county and not below it. So they describe the county around Wentzville (St. Charles County) rather than Wentzville itself. Neither is part of the Area Score. How to read crime rates and death rates.
