Facebook insights of my own fanpage

I have been managing a personal Facebook fanpage since a year ago about my travel-study experience in New York. I share mainly photographs I took in NYC; sometimes I post about my student life in Albany, and sometimes my own drawings. Since I'm from Taiwan, I usually write the story and picture captions in both mandarin Chinese and English.

For your personal interest, here is my fanpage: http://on.fb.me/14Beo5x

It's pretty amazing to see and fun to study all the Facebook insights that FB provides you every week. There are so many terms such as "virilality", "reach" which can be very confusing, but it does help you understand the demographics of your fan-base. It even shows how many people unliked your page during the past week. I find it interesting how among the fans that liked my page, there are much more female fans than males. This also seem to be true for other friends of mine, who also own fanpages telling their travel stories... (I wonder if there are insights that will help answer this question?)
