By Sysomos Inc.


Over the past few months, Twitter has experienced explosive growth, attracting celebrity users such as Oprah, and a growing mountain of media and blog coverage. Sysomos Inc., one of the world’s leading social media analytics companies, conducted an extensive study to document Twitter’s growth and how people are using it. After analyzing information disclosed on 11.5 million Twitters accounts, we discovered that:

  • 72.5% of all users joining during the first five months of 2009
  • 85.3% of all Twitter users post less than one update/day
  • 21% of users have never posted a Tweet
  • 93.6% of users have less than 100 followers, while 92.4% follow less than 100 people
  • 5% of Twitter users account for 75% of all activity (see the report on analysis of top-5% users)
  • New York has the most Twitters users, followed by Los Angeles, Toronto, San Francisco and Boston; while Detroit was the fast-growing city over the first five months of 2009
  • More than 50% of all updates are published using tools, mobile and Web-based, other than TweetDeck is the most popular tool with 19.7% market share.
  • There are more women on Twitter (53%) than men (47%)
  • Of the people who identify themselves as marketers, 15% follow more than 2,000 people. This compares with 0.29% of overall Twitter users who follow more than 2,000 people.

“We wanted to take an extensive snapshot of Twitter that goes far beyond anything done to document Twitter’s use, growth and demographics,” said Nick Koudas, Sysomos’ co-founder and chief executive. “While Twitter’s growth has been well documented, we wanted to put the spotlight on how people use Twitter, as well as identify many of the key trends in their backgrounds, demographics and activity. Our study, based on the most comprehensive dataset of Twitter users, provides a wealth of information for anyone interested in getting in-depth details about Twitter.”

Twitter’s Hockey Stick-Like Growth in 09

The Facts: Since the beginning of the year, 72.5% of Twitter users have signed up for the service. This includes 22.7% of total users in March and 19.7% in April.

So what accounted for the tremendous growth in March and April? In March, Twitter started to attract significant media attention after reported that the number of Twitter users had skyrocketed in February.

In April, Twitter’s profile was enhanced when Ashton Krutcher (aka @aplusk) waged a public race against CNN to be the first to have one million followers. Then, on April 17, talk show celebrity Oprah Winfrey (aka @oprah) started using Twitter, making her first Tweet on her show with help from Twitter co-founder Ev Williams.

Although April did show impressive growth, it was also the first time in nine months that Twitter had a decline in month-over-month growth.
