Facebook will post its slowest US user growth ever in 2021

In 2021, the number of monthly Facebook users in the US will increase by less than 1% year over year, the platform’s lowest annual growth rate to date.

Much of this deceleration is due to last year’s faster-than-expected growth of 3.3%, which was driven by changes in media habits during the pandemic. That helped to push future accelerations forward, and as a result, Facebook will see slower user growth for the rest of our forecast period, which ends in 2025.
