A latest study conducted by the Pew Internet and American Life Project says that those who use Twitter are relatively younger. A survey conducted during the study, which involved 2,253 online respondents found that nearly 20 percent of adults' ages 18 to 34 years old have used so-called micro-blogging sites, of which Twitter is the best known.

However people who are over 35 years of age do not believe in Twittering. The study concludes that only 10 percent of those 35-44 years old use the services and a scant
5 percent of those 45- to 54- year-olds are users.

Furthermore, lower-income households are represented in greater numbers than upper-income families. "Nearly 17% of internet users in households earning less than $30,000 tweet and update their status, compared with 10 percent of those earning more than $75,000 annually," says the study.

A correlation between younger adults earning less than older individuals is also made by the study.

The study says that users who use wireless are more likely to use Twitter. "Fourteen percent of users who access the Internet wirelessly via a laptop, handheld or cell phone have used a service like Twitter, compared with 6 percent of users who go online through a wired connection. They are also less likely to read a printed copy of a newspaper, but more apt to read a newspaper online (76 percent vs. 60 percent of non-Twitter users)," says the study.

It was found by the report that the use of Twitter is related to the use of other social media and Twitter is more likely to be used by those who blog or use social networks.

It was confirmed by nearly one quarter (23 percent) of social network users that they have twittered or used a similar service. It should be noted though that only 4 percent of those who do not use social networks have ever used such services.
