I live in Chicago and yeah you have to be carful but that's any big city! I'm only 17 so it's not like I have a lot of experience but nothing bad has ever happened to me. I always hear about people getting robbed and stuff but again.. That's every big city! Chicago's awesome:)
Chicago isn't even close to safe. Take the deaths of US Military alone in Afghanistan, and it will closely match the number of murders in Chicago. I'd rather live in Detroit (not that you'll ever catch me living there)
I live in Chicago and it's pretty safe. Thankfully, I've never witnessed a crime nor have I heard of one occurring anywhere close to where I live. Of course it depends on where in Chicago you are. Chicago is large. Just like any city, there are safe places and dangerous places. The North part of Chicago (mostly the suburbs) are pretty safe. The south-side is dangerous. Don't go there. I love Chicago! Over all, I think it's great. The crime rate may be high, but that's not in every part of Chicago. It's just mostly in the southern part, like I said.
