Facebook Group: Find the Top 3 Nationalities represented by the fans

Hello,

How can one quickly determine the top 3 nationalities represented by a group of about 500 fans, without having to click through to each fan's page?

On Facebook? I'm not sure you can: I don't remember entering my nationality on my profile...

I would guess there must be some way of putting a poll up and asking the people in the group to take it.
