I came through this interesting chart this morning that shows the demographic split of Twitter users by age.
Fascinatingly the speediest growing segment on Twitter (other than bots) is amongst people 24 and younger accelerated more rapidly than older folks in 2009, according to comScore.
Not like most social networks, Twitter began out being more well-liked with adults, before it caught on with younger users. Previous year that changed as celebrity tweets caught on, and mainstream media began talking about the service more.
Towards the end of 2009, more than 30% of Twitter’s visitors were under 25, this chart suggests, up from about 20% of its visitors towards the end of 2008.
As you can see from the chart above, over 30% of Twitter’s visitors were under 25 up from about 20% of its visitors at the end of 2008; thank you in fraction to celebrity adoption and the mainstream media mentioning Twitter.
