Just for curiosity I counted the number of "active" players that have appeared at the MLB level based on which state they were born in. Baseball Almanac actually has that info. I checked about 10 states (see below), but anyone can check any state they want at the Baseball Almanac site.
Here are the results from the states I checked...
California - 230 (WOW!)
Texas - 118
Florida - 110
Georgia - 51
Illinois - 37
New York - 32
North Carolina - 27
Virginia - 23
Arizona - 22
New Jersey - 21
Of course, this is just one way to look at things, but still kind of revealing IMO.
