I am from Chicago and watching the Hawks vs Islanders and this question popped into my head. Typically "North Siders" like the Cubs and "South Siders" like the Sox (which obviously is not all encompassing- I also think certain demographics and socioeconomic factors influence as well, which also is not all encompassing!) I was wondering- does ones birthplace influence what team New Yorkers typically like? Is it a socioeconomic thing? (For instance; what neighborhoods like Yankees vs Mets)?
