To identify the safest cities in Illinois, SafeWise reviewed the 2015 FBI Crime Report statistics and population data. They eliminated all cities with fewer than 5,000 residents as well as any cities that failed to submit a complete crime report to the FBI. From there, they evaluated the remaining cities. SafeWise narrowed the list down based on the number of reported violent crimes (aggravated assault, murder, rape, and robbery) and property crimes (burglary, arson, larceny-theft, and motor vehicle theft) in each city. To level the playing field, they calculated the likelihood of these crimes occurring out of 1,000 people in each city.
The average violent crime rate among the cities—large and small—on the list was 86% lower than the national average. Property crime rates were also exceptionally low among these safe communities. No city cited more than nine property crimes per 1,000 residents—with the average rate being about six crimes per 1,000 people. That’s 77% lower than the United States average.
