I would go by the local law enforcement office or sheriff's office and speak to them. They should have statistics on the quantity and type of crimes in the area. The other thing to do is speak to the neighbors, if they've lived there long enough, they should be able to give you some insight.
It depends on the area. I've lived in the Port Richey area for 18 yrs and the worst problem I've had was once kids stole my mail; getting a security mail box fixed that situation. I suspect lack of jobs contributes, but mainlly the people who live in this area don't complain enough to the County; no activism here.
