Why don't you contact the Bridgeton PD...they could be of great help. At least telling you the area's that are safer than others.
Also in the Maryland Heights area... I would do the same thing.
They have a brand new state of the art city hall, it's really nice, (I know people that took a tour thru it) you could check with them as well.
Also local realtors would give you some ideas.
Another thing to consider...not knowing your age, so please don't be offended. M H use to have a Seinor Center, the St. Louis county parks & Rec. were in charge of it. I believe Bridgeton still has their Sr. citizen club & I know St. Ann does, but I don't advise even looking in St. Ann area to live in.

If you contacted these, I know you would get some help.
You could also call chamber of commerce in these areas.
Good luck
