Well, if you have to ask....

No really, if you are worried about shady characters that is probably not the best place to move to. The neighborhood is drastically improved from years ago but there is still a pocket of drug dealers and other dregs that will never leave unless the city sells of the PHA housing in the area (which ain't gonna happen).

I doubt if you are at much greater risk than anywhere else in Spring Garden/Fairmount though. Most of the problems are basically internecine violence between people who know each other and not directed at random victims.
