this is an old post, but i was just very curious since i've had a couple of friends from chicago, and it seems like the latinos there are mostly mexican with a few other groups represented here and there, but only marginally. thanks for the information. living in florida, and growing up in ny, i'm kinda spoiled in that there are so many neighborhoods with lots of ppl similar to myself. it was hard for me in philly (not too many latinos in PA); i'm pretty sure that Illinois has similar demographics. thanks for the share.
