LinkedIn had 160 million active users, up 20% in two months

LinkedIn, the social network for professionals, had 160 million monthly active users in November, according to the latest figures available.

That was an increase of nearly 30 million from September when LinkedIn had more than 133 million users who logged in to the website at least once a month.

The Mountain View, Calif., company announced the number, which was calculated by research firm comScore, after crossing the mark for 200 million registered users earlier this month. LinkedIn has registered 13 million users since November.

LinkedIn launched in 2003 and hit 100 million registered users in March 2011. The social network has been able to keep growing steadily since going public in May 2011. Its stock price has increased by 25% since then and stands at $117 per share.

With 160 million active users, LinkedIn is in front of Google+, which last month announced it had 135 million active users and more than 500 million registered users. Twitter, meanwhile, had more than 200 million active users as of last month.

And, of course, Google+, LinkedIn and Twitter all fall behind Facebook, which has more than 1 billion monthly active users.
