Overall, Monmouth grades C+ for safety (#222 of 339 graded towns in Illinois): close to the middle of U.S. towns, on crimes its police reported to the FBI in 2023–2025.
Crimes reported to the FBI per 1,000 residents a year, 2023–2025. “Rest of IL” is every other Illinois 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.
What’s behind Monmouth’s grade
Property crimes plus four times violent crimes reported to the FBI per resident, 2023–2025, on a national curve. Both violent and property crime are higher than in most U.S. towns; property crime is the closer of the two to typical. Its violent rate (2.4) is below the FBI’s national estimate (3.6) but higher than in most individual towns: the national figure is weighted by people, and the grade counts towns. Its property rate (12.0) is below the FBI’s national estimate (17.6) but higher than in most individual towns: the national figure is weighted by people, and the grade counts towns.
Violent crime, by year and by type
Monmouth’s police reported 61 violent crimes to the FBI over 2023–2025, about 2.4 per 1,000 residents a year, against 3.1 in the rest of Illinois and the FBI’s national estimate of 3.6.

Three people died in crashes on Monmouth’s roads in 2019–2023
Monmouth had 2 fatal crashes in five years, in which three people died; 1 was a pedestrian.
That is about what is typical for Illinois towns of 5,000–25,000 people: at their median rate (6.8 deaths per 100,000 residents a year), a town of Monmouth’s size would see about 3 in five years. With numbers this small, a death or two either way changes the picture, so Monmouth’s own rate (7.0) is context, not a ranking.
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 Monmouth. 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 Monmouth’s residents, which raises the per-resident rate.
- Whose population. Rates use the FBI’s population for the department (8,571 in 2025); our figure for Monmouth is 8,599 (2025 Census estimate).
- Gaps are real gaps. A missing year means the department didn’t report a full year, not that nothing happened.
