Safety Context Score: 52/100 (Grade C)
CrimeContext scores Ontario on a 0-100 scale that weights per-capita violent crime against the national average (40%), per-capita property crime (30%), and the 5-year direction of total crime (30%). A grade of C means Ontario sits roughly in line with the typical U.S. city once population is taken into account. Crime has been trending upward over the past 5 years.
We never display raw crime counts. A large city will always log more total incidents than a small town; the only fair comparison is the rate per 100,000 residents, which is what every number on this page uses.
