Oh, You are asking for statistics data for the content of your blog like those from Statista, Pew research, YouGov etc. Those are some of the easily accessible statistics data, often free or for a small fee. There are number of other statistics agencies which offer data for significant fee to the corporates.
You said 2002, So was it some specific topic for which you couldn't find latest statistical data?
P.S. @Moderator , I think the problem statement should be updated.
