The match doesn't break down stats by geography to my knowledge, and individual programs aren't going to disclose that information.
As far as Chicago, Loyola is typically easy to match because it carries a malignant reputation. UIC is also not particularly competitive and has a better reputation. Rush and UofC are reasonably competitive, and Northwestern is pretty competitive (though still nowhere near as competitive as somewhere like UCSF or Partners would be). So if you're reasonably competitive for neurology as a specialty in general, you probably won't have any trouble matching into Chicago specifically. That leaves 3 that are evidently new or small enough that I've never heard of them despite living only a few hours away.
