How many monthly active users did Facebook have as of Q4 2023?

Facebook had 3.07 billion monthly active users as of December 31, 2023.

Meta reported the figure in its fourth-quarter and full-year 2023 results. It represented a 3% year-over-year increase and measured people active on Facebook during the relevant monthly period. The figure is a quarter-end snapshot, not an average for every month of the year.

This number should not be confused with Meta’s broader family-of-apps audience. Across Facebook, Instagram, Messenger, and WhatsApp, Meta reported 3.98 billion monthly active people at the end of 2023. That larger figure counts the company’s combined ecosystem rather than Facebook alone.

Meta also later changed its reporting approach, moving away from the older Facebook-specific MAU and DAU metrics in regulatory filings. For that reason, 3.07 billion is best understood as a historical figure tied specifically to Q4 2023, rather than a current user count.
