The number of Twitter users who accessed their account at least once a month fell in the first quarter of 2019 to 330 million. That was down from a record high of 336 million monthly active users (MAUs) in the first quarter of 2018.

Monetizable Daily Active Users

Starting in the second quarter of 2019, Twitter stopped reporting MAU figures and instead began utilizing monetizable daily active users (MDAUs) as its primary reporting metric. Twitter defines MDAUs as "Twitter users who logged in or were otherwise authenticated and accessed Twitter on any given day through or Twitter applications that are able to show ads."

Twitter reported average MDAUs of 139 million in the second quarter of 2019, up from 122 million in the second quarter of 2018. The number of average MDAUs rose to 145 million in the third quarter of 2019, up from 124 million a year earlier. The figures for the year-earlier periods hadn't previously been publicly released.

Changes in MAUs

MAU figures dating back to 2008 show rapid growth in the early years—200% in 2009 and 2010—with steadily decreasing growth rates thereafter: from 116% in 2011 to 2% in 2018.

Users by Country

As of July 2019, there were 48.6 million MAUs in the U.S. The countries with the next largest numbers of Twitter users were Japan, with 36.7 million, and the U.K., with 14.1 million.

Demographics for U.S. Users

The percentage of U.S. adults who reported using Twitter was 22% in early 2019, down slightly from a year earlier. For those 18 to 24 years old, that figure was double the overall statistic: 44%. Among those 25 to 29, the figure was 31%, and for those 30 to 49, it was 26%.

Eighty percent of all tweets originating in the U.S. are sent by the 10% of U.S. users who are most active. The median number of tweets those top users send a month is 138. Their median number of followers is 387, and the median number of accounts they follow is 456. Sixty-five percent of those top tweeters are women, and 42% of them said they had tweeted about politics within the last 30 days.

Forty-two percent of adult U.S. Twitter users have at least a bachelor’s degree; that's 11 percentage points higher than for the overall population. Adult Twitter users in the U.S. are also wealthier, with 41% of them reporting a household income above $75,000, compared with 32% for the population as a whole. The gender and racial or ethnic makeup of adult U.S. Twitter users doesn't differ significantly from the general population, according to Pew Research.

Tweeters With the Most Followers

As of September 2019, former U.S. President Barack Obama had the most followers: 108.2 million. Pop singers Katy Perry and Justin Bieber weren't far behind, with 107.9 million and 106.4 million, respectively.

Twitter had its first profitable quarter in the fourth quarter of 2017. It earned $91 million on $732 million in revenue.

Twitter had its first profitable year in 2018, when it earned $1.2 billion on more than $3 billion in revenue.
