Facebook UK loses 600,000 users in December

Numbers dropped by 1.86% over festive period, fuelling speculation that site is reaching saturation point in core markets

The number of Facebook's UK users dropped by 600,000 in December, according to data by social media monitoring firm SocialBakers.

Though representing a typical seasonal dip in use over the Christmas period, the UK was the only one of Facebook's 10 busiest territories that saw a seasonal fall, with user numbers dropping 1.86%.

On SocialBakers' index the UK ranks as the world's sixth most active Facebook user base, with more than 33 million unique users in December, although that figure duplicates users who access from multiple devices.

That user base would be equivalent to 53% market penetration last month, second only to the US with 54%. The US tops the list with more than 169 million unique users per month, followed by Brazil with 65 million and India with 63 million.
