What's the quickest way to findout answers to following questions about facebook users:
1- How many male computer science graduates from my *university* aged between 18 and 25 are registered on facebook?
2- How many male computer science graduates from my *country* aged between 18 and 25 are registered on facebook?
3- How many *female* graduates from my university aged between 18 and 25 are registered on facebook?
4- How many graduates from my university are registered on facebook?
The quickest thing that came to my mind was to use the API somehow, however there is something else that facebook wants advertisers to use to answer such questions!! But hey, anyone can turn out to be an advertiser on facebook :D
So, yeh! it's pretty easy and thanks to Alec Saunder for innovating this trick!
To answer countably infinite such questions, follow the steps that he has neatly outlined on his blog here.
Summarizing it, there is no big trick here. Each advertiser is facilitated by facebook with a query builder that immediately returns *ONLY* the number of results of a specific input query. With a little investigative approach and excessive show of curiousity, you can use this tool to build a strong data set of facebook statistics, which by all means, can be called a representative sample of all the world wide web users!
Following is a depiction of my lack of creativity to use this tool, :p
There are 2440 18 year old males from China registered on Facebook.
There are 1,143,180 18 year old males from USA registered on Facebook.
There are 31,020 18 year old males from India registered on Facebook.
There are 11,400 18 year old males from Pakistan registered on Facebook.
There are 267,760 18 year old males from UK registered on Facebook.
