Indonesia still heads the table for the world’s fastest growing Facebook population, clocking up nearly 1.2 million new signups a month and gaining the world’s third-largest overall Facebook population as of June 2010 (after USA and UK). Inside Facebook‘s Global Monitor report notes that, at only half a million users behind the UK, Indonesia should be world #2 before too long.

Other Asian countries are also looking good in the latest Growth Top 10: India is in second spot with 989,640 newbies, Philippines is third (842,880), Thailand fifth (459,340) and Malaysia sixth (434,580).
