The best way to get answers to crime questions is to consult with the local police or sheriff department.
Sometimes they post this data online and sometimes you can find crime history maps and data through local newspapers or their websites.
You could also talk to current residents. You might be surprised to find you'll get a lot of candid info if you visit a neighborhood and introduce yourself and talk to people.
If you're comfortable doing that, you'll learn a lot. If you're hesitant about doing that, you may already have your answer based on your gut instinct.
