Quick Stat: 132.5 Million People in the US Will Log In to Facebook Regularly This Year

Facebook usage has grown steadily in the past two years and will continue on a solid trajectory. eMarketer estimates that 132.5 million people in the US will be using the service this year; by 2013, that number will increase to 152.1 million.

This growth will be driven primarily by increased Facebook use among older boomers and seniors. At the same time, teens and young adults will continue to form the core of Facebook’s audience, with penetration rates among these groups ranging from 80% to 89% of internet users by 2013.
