How many NBA players were born in Chicago?

I don't know 'how many' NBA players were born in 1963. But one thing I know is that 1963 was the year that produced a huge number of legendary NBA players. Michael Jordan, Hakeem Olajuwon, Charles Barkley, Karl Malone, Charles Oakley, Chris Mullin, Joe Dumars, Terry Porter, Jeff Hornacek, Detlef Schrempf... to name a few.
