In any city there area areas where crime is more active and areas where crime is almost non existent. Jacksonville (Duval County) and St. Augustine (St. Johns County) is no different than any other city.
The best way to get infomration on crime is to contact the Sheriff Department Zone Commanders. The infomation you receive will be more accurate to the specific areas you seek and the answers more direct than what a Realtor can legally discuss.
