Are there more Cubs fans or White Sox fans?

I have been wondering how many actual Cub fans and Sox fans there are. Fans and the media make it seem like there are so much fewer Sox fans. I have been conducting personal research to determine the reality of this. I documented 33 friends of mine.

81% are Cubs fans
18% are Sox fans

I took a look at the 2010 attendance numbers - the % of people attending pro ball in chicago in 2010
59% of people that attended a pro MLB game went to a Cubs game
41% of people that attended a pro MLB game went to a Sox game

I also looked at TV ratings. The % of people watching pro MLB ball in Chicago in 2010
59% of people that watched a pro MLB game on the TV watched a Cubs game
41% of people that watched a pro MLB game on the TV watched a Sox game

Conclusion: there are more Cubs fans than Sox fans in the Chicago area
