In St Louis, we have a Central West End, but I've never heard of an area that is referred to only as "West End". We do have an area that is known as Visitation Park that is north of Delmar, west of Union, east of Belt and South of Maple, but I"m not sure if that's the area that you are talking about. The Visitation Park area in St Louis is actually a Historic District and has some lovely homes in it, many of which have been renovated, but there are also some brand new housing developments being built in the area.
In terms of the crime rate, I will refer you to the St Louis City website http://www.slmpd.org/crime_stats.html which gives the crime stats by neighborhood, district and ward.
The area is home to St Louis City Public Schools, including magnet schools such as Soldan International Studies High School and some private/parochial schools.
