What is the level of security in Chicago?

It is a very fine city, though not very safe. It has quite a high crime rate, and when I went there I saw quite a few places with barred windows. Not the best for a family, but if Its just you or just you and your spouse, then it will be a great place. The security: on a scale from one to ten, I'd rate it 6/10 safety. New York and others get much more crime, thus others resulting in 9's and 10's. Anyway, you should be good, depending on what part of Chicago you go/move to. I sure hope this helps!
