I second the Illinois side. All the benefits of the city, being ten miles away, but with farms, woods, and suburbia at your fingertips. (You can get that on the west side of St. Louis, too, but since white flight settled there first, you’ll have to live much farther from downtown to be anywhere near nature or the country.)
Stay away from “East Saint Boogie”, Sauget, Washington Park, Venice, Brooklyn, and other “towns” directly on the east riverfront. The next layer of towns over (Caseyville, Belleville, Collinsville, Maryville, Edwardsville, Glen Carbon, Granite City) are all right. Caseyville (where I live) and Granite are marginal suburbs, poorer than the others I mentioned, but considerably safer and less bleak than East St. Louis or Washington Park. And the living is cheap!
No, it’s kind of the opposite. St. Louis City split itself off from St. Louis County in the 1870s. Which made some sense at the time. But now it means all the safe, well off gentrified areas that offset crime statistics in other cities are now technically not part of the city at all. Which leaves the poorer, more crime ridden areas within the city limits over represented in the statistics. St. Louis has plenty of crime and poverty issues, but I think “murder capital of the world” is just a statistical artifact. I feel as safe there at night as I do in other cities. Don’t join a gang or try and screw people on large drug deals and you’ll probably be perfectly safe.
Nope, that’s Collinsville, ten miles away from Cahokia, IL. Collinsville is the horseradish capital of the world. And also, once, the center of the largest and most important civilization in North America. Also, Mike Stipe of REM went to high school there with my mom.
For reference, my friends and I found this map surprisingly accurate. But all the good parts of the metro east are not shown.
