As COVID-19 began sweeping across the world last spring, Twitter experienced phenomenal growth with much of the planet’s population confined to their homes, helping the platform recover from a seven-year slump in daily tweet volume. As the pandemic has worn on, has Twitter continued to grow? How did the changes the platform made around the 2020 presidential election affect its growth and has its banning of Donald Trump caused it to lose users?
While Twitter itself does not publish detailed usage statistics, it is possible to estimate its growth from the daily random sample that it makes available of 1% of all tweets, which is highly correlated with its actual growth. Using this approach, the timeline below shows the estimated number of tweets per day on Twitter from Jan. 1, 2012 through Jan. 5, 2021 (gaps are days with missing data).
Since its peak in July 2013, Twitter was on a years-long decline through the end of 2018, but had begun slowly growing again over the course of 2019. Then, in the space of just two weeks in the middle of March 2020, as lockdowns swept the world, the platform grew by almost 100 million tweets a day, rising back to its July 2013 numbers.
The timeline below zooms into the Jan. 1, 2020 through Jan. 5, 2021 period, showing this phenomenal growth. Even as lockdowns eased across the world earlier this year, Twitter use did not decline, showing remarkable staying power. From Oct. 7-20, daily Twitter volume increased another 50 million tweets a day as all eyes focused on the U.S. election, then suddenly dropped by around 70 million tweets a day almost overnight on Oct. 21-22, and only began to recover on Dec. 17. What might explain this strange anomaly?
