I am from Sao Paulo, Living in Miami and everyday i go shopping i hear people speaking in Portuguese (Which you can't even compare to the amount speaking Spanish, more then half the people speak spanish)
I was surprised when i didn't see Sao Paulo in the top ten list for most buildings and when i searched for it on skyscraperpage.com i got this (
http://skyscraperpage.com/cities/?10=2 ) 306 buildings I can see much more then that from my grandmas house there!
Emporis lists 5,453 buildings and 556 U/C which is correct (

Sao Paulo probably had more then 306 buildings in 1947 let alone 2008 - Look at the pictures from that date:

*(I sent a email early 2008 requesting a change in the Sao Paulo building count but nothing happened)
