Is there a known guy/gal differential on Foursquare in these cities? If so, it might be nice to have the ability scale these scores to reflect that.

In other words, if 2/3 of SF's Foursquare users are female and 2/3 of a particular SF bar's Foursquare users are female:

1) It's true that the guy/gal ratio is 2:1, but

2) It's also true that there is no enrichment of women at this bar relative to the null expectation.

Edit: A collection of presumably neutral places (e.g., Bay Bridge) might help achieve such an estimate.

carbo,

all percentages shown are deviations from our calculated average per city, so there is an average of about 2 male checkins per 1 female checkin in SF. hope that clears it up a bit!
