Looking For Statistics ... About Bkk

Hi!

and my respects to all the people here who have explained so many things in this forum, before I even asked : )

But now - can anyone recommend some web resources (if any available) with some statistics about bkk (about the www-activity first of all).

To be more specific : the main data I`m looking for :

Internet users among people aged 15 - 25, also other groups, if possible

It also would be nice to find some numbers about the average salaries etc. But this data should concern only Bangkok, not other parts on this fine country.

I hope someone sees where I`m going with this. Main question beeing - are there some stats available, covering only bkk.

thank you!

John
