Here's a correct site. There is a book ... "Places Rated Almanac" ... that rates various cities on multiple criteria ... crime rate is among them ... as all right as cost of living, etc.
Neighborhood ratings on crime come from local police departments ... try your city home page ... some have it - some don't.
Most of the local sheriff departments are publishing crime statistics for local areas on their pattern site up my street does it all I surmise
Try entering your address at this site & see what comes up:
