Facebook had 432 million mobile monthly active users as of December 31, 2011, according to an updated filing with the Securities and Exchange Commission. The company also revealed that just over 13 percent of these users accessed the social network exclusively through mobile devices.
When the company filed for an initial public offering in February, it said it had more than 425 million mobile MAU in December 2011. Now that Facebook has updated stats through the end of 2011, it notes year-over-year mobile MAUs growth of 76 percent, from 245 million as of Dec. 31, 2010 to 432 million as of Dec. 31, 2011.
The company estimates that 58 million users accessed the social network solely through mobile apps or the mobile website during December 2011. It did not note what percent of these users are on feature phones versus smartphones, nor did it provide any demographic information about these users. In India, for example, many people access Facebook from phones when they don’t have personal computers. The remaining 374 million mobile MAUs accessed Facebook from both PCs and mobile devices during that month. The social network says it has 845 million total MAU.
In its SEC filing, the company wrote:
We believe that our mobile MAU growth was also driven by product enhancements across several mobile platforms. For example, we improved our product offerings on feature phones following our acquisition of Snaptu in April 2011 and we launched the Facebook app for the iPad in October 2011. Improving our mobile products and increasing mobile usage of Facebook are key company priorities that we believe are critical to help us maintain and grow our user base and engagement over the long term.
