Growth may be no surprise when it comes to Facebook, but it seems as if the California based social networking giant will be reaching 700 million users soon according to some analysis done by the Socialbakers Facebook statistics site.

Countries such as Brazil, Phillipines, Indonesia, Mexico and Argentina are responsible for much of the social website’s international adoption recently. According to Socialbakers’ statistics, almost half of the U.S. uses Facebook already, with 149 million users. It makes sense that the company would be concentrating on tapping overseas growth since America is a spent vein.

Indonesia has the second largest amount of Facebook users at the moment with 37 million, but the countries with the most significant amount of growth in the month of May are Brazil and Egypt with 11%.

What is interesting about Brazil and their 1.9 million new users is that the country already has a dominant social networking site—Orkut. This site bombed when it came to the U.S. but has more than 100 million users worldwide, split almost evenly between Brazil and India. With these two countries in the top 10 list of growing Facebook users, the Google owned Orkut may be seeing it’s demise in the face of Facebook’s momentum.

Along with the 700 million worldwide users, the Washington Post reports that the site is expected to host 100 billion photos once summer rolls around. According to their statistics, close to 6 billion photos are uploaded monthly with female users taking part in the majority of the picture uploading. The Post says “the number of profile photos posted on Facebook has tripled since 2006”.

700 million users really isn’t that many people when you think about the Earth’s current population of 6.8 billion. Facebook still has a ways to go before it takes over the world.
