How CrimeGrade™ works
The property crime CrimeGrade™ covers burglary, theft, car theft, arson and vandalism, from A+ for the least crime to F for the most, on one scale for the whole country.
It weighs each property crime against what it affects: homes for burglary and arson, parked cars for car theft, and the people and parking around stores for theft.
The rates on this page count crimes for every 1,000 people who live here, the way police departments report them. Black Diamond is the other kind of example: few people work in, shop in or visit it, so its crime per resident looks lower 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.
Where the numbers come from
Crime reports that police departments file with the FBI
State crime records and city crime data, where they are published
Published research on what crime costs victims and communities
These are estimates of reported crime for whole areas, not a record of what happened on any one street. CrimeGrade™ updates them once a year and provides them free and without guarantee. Check local sources before you rely on them for a decision.
