Facebook lost 6 million users in the U.S. last month

Data from independent traffics firm Social Bakers and reported in The Guardian shows that Facebook isn't just shedding users—the ones its keeping are spending less and less time on the site. Traffic in the United States fell four percent over the past month, with Facebook losing 6 million users. That trend was consistent across international borders: In the U.K., the world's largest social network lost 1.4 million users, a 4.5 percent decrease.

In December, American Facebook users logged an astonishing 121 minutes on the platform—but by February that had fallen to 115 minutes, according to ComScore.

Web analytics firms Alexa and Quantcast both show a traffic drop for Facebook over the past few months.
