I grew up there and at 12 (50’s) got bus and street car transfers all over the city. NW Baltimore is probably the most dangerous.
Your information is without a doubt dated. The only "safe" areas now are near the inner harbor and along the water to Canton, South Baltimore and the center section along Charles St is not bad, but property crime is rampant there. The rest is pretty dang dangerous, and its creeping into the suburbs
East Baltimore is among the most dangerous parts of the city. It leads the city's other police districts with 41 homicides as of Oct. 8, an increase of 11 percent from the corresponding time last year, and 98 nonfatal shootings, an increase of 17 percent.
In fact, they were talking of taking measures some people refer to as martial law .
