How CrimeGrade™ works
The violent crime CrimeGrade™ covers murder, rape, robbery and assault, from A+ for the least crime to F for the most, on one scale for the whole country.
It weighs each violent crime against the people who spend time in an area, so a busy downtown is graded on its workers and visitors as well as its residents.
The rates on this page count crimes for every 1,000 people who live here, the way police departments report them. Thornhill is a good example: many people work in, shop in or visit it, so its crime per resident looks worse than its CrimeGrade™ suggests.
Comparisons with US neighborhoods use the Census Bureau's block groups, small areas of about 1,400 residents, and count the people who live in each. The figures count crimes reported to police; many crimes, shoplifting above all, never are. Behind the grades, CrimeGrade™ tested 21,607 factors from 125 data families. For business owners, paid CrimeGrade™ location reports estimate crime at a single address for each type of business.
