Facebook now has 750 million monthly active users worldwide, TechCrunch reported on Friday. That’s incredible growth since our June 1st story, which suggested that the social network was closing in on 700,000,000 users worldwide. In that report, emerging markets showed the most growth — Brazil’s user base jumped 11.4% in May alone — and the United States was the top country; U.S. users were responsible for 149.4 million Facebook accounts. Last July, Facebook announced that it had hit the 500 million user mark, but it hasn’t publicly revealed any figures since then. Facebook only measures active users and only counts those who have logged into the social network during the past 30 days. Also Read - What happens to your Facebook account after you die?
