About This Statistic
This statistic displays a forecast of the development in Facebook user numbers in the United Kingdom (UK) from 2014 to 2021. In 2021, the number of monthly active Facebook users is projected to reach 41.37 million individuals. This would be an increase of over six million new users from 34.99 million users in 2015. This would mean a 7.93 percent increase in Facebook's UK user penetration rate to an expected 61.89 percent in 2021. Included are all Facebook accounts that get used at least monthly via any device. The rate of use in the United Kingdom is the second highest penetration rate in the EU according to Statista's own data.
These numbers reflect Facebook's dominant position on the UK social media market, where the company reached a market share of 87.08 percent in January 2017. By now the services offered through Facebook reach all age groups in the country but slightly more female users than male users. Facebook gets used more than once a day by around 44 percent of the UK online population. Only 21 percent of UK adults that go online don't use Facebook at all.
