Hi Erin. While I mostly agree with Anna below, I differ on the concept of steering. You're asking about neighborhoods to avoid while walking at dusk with your child, not what are some area to not consider when looking to purchase. However the basic point is the same.
As Licensed professionals, we are not allowed to comment on an area as good, better, best or how safe. That is discrimination and it is illegal. Anna does give great inforation in that you could always check crime stats. You could also go into neighborhoods at various times of the day and night to get a "feel" for them and your perceived level of safety. Good luck.
