Jenny gave you the websites you can check. You see, agents aren't allowed, by law, to discuss things of this nature.
One tip I give every buyer I work with is this: if you are curious about how comfortable you'd be in an area, drive around in the evening and see what the neighborhood seems like. I just had an investor who was going to buy a nice little rental property, but he was concerned about some apartments that were nearby. Not only did he drive around at night, but he knocked on neighbors doors and asked how they felt about crime and safety in the neighborhood. This helped him make an informed decision.
Hope that helps!

Good luck and stay safe :)
