United States 43.11%
Brazil 15.02%
Japan 5.66%
Netherlands 3.49%
United Kingdom 3.28%
India 2.97%
As on 5/14/2004 as claimed by a post on http://www.orkut.com/CommMsgs.aspx?cmm=34264&tid=5622

Indian presence is growing faster than Orkut's growth. And given India's population, I figure there's still room for a lot of growth.

Do you know what could cause the rapid growth of orkut in India ??
