We all know that there millions of users of the micro blogging site Twitter, but it seems that while there are millions of users it seems that no all of these users are active users. this can be seen in the image below with a sample of 100 users where the figures show exactly how many are tweeting, idle and have some serious followers, as in real life it seems that only a small percentage are totally active.

These are some of the figures that were knocking around in 2009, naturally, these figures have changes quite a bit, but we suspect that the actual percentages could be the same!

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 Twitter.com. TweetDeck is the most popular non-Twitter.com 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.
