Social media usage gains from 2020 have largely ended. Facebook will have its lowest growth rate ever, Instagram’s user base is getting older, and Twitter is coming down with a case of post-election malaise. However, TikTok and Reddit are still attracting users at an accelerated pace.

Social media usage, advertising, and commerce will reach new levels in 2021, presenting big opportunities for brands to engage consumers.

The pandemic has fueled greater social media usage worldwide and prompted revisions to our earlier forecasts. We now expect the total number of social network users to rise 8.1% in 2020, to 3.23 billion—equivalent to 80.7% of all internet users.

As with other social networks, Twitter’s user base grew unexpectedly this year as pandemic-driven stay-at-home orders drove up social media usage overall.
