How CrimeGrade™ works
A CrimeGrade™ shows how much crime an area has compared with the rest of the country, from A+ for the least crime to F for the most. Every neighborhood in the US is graded on the same scale, so a B in St. Louis County means the same as a B anywhere else.
CrimeGrade™ starts from the crimes people report to police and measures each kind of crime against what it affects: people for assaults, homes for burglaries, parked cars for car thefts.
The rates on this page count crimes for every 1,000 people who live here, the way police departments report them.
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.

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.
