The analysis released Wednesday, called “Generations Online in 2009,” is based on 11 separate telephone surveys conducted between 2004 and 2008, with varied questions about Web activities, ranging from blogging to participating in an online auction to job research. The margin of error for the studies ranges from plus or minus 3 percentage points (for findings on adults) to plus or minus 4 percentage points (for findings on teens.)

“Generation Y is the most likely to be engaged in all the various activities — communication, entertainment, e-commerce and entertainment-seeking,” says Susannah Fox, the report’s co-author and associate director of the Pew Internet & American Life Project. Pew defined Gen Y as including ages 18-32.

She says Generation X (ages 33-44) uses the Internet to “take care of business,” with 67% banking online; 80% buy products online, compared with 71% in Gen Y. The 33-44 age group also use the Internet for watching videos and socializing, but less so than Gen Y.

“Generation Y is starting to get into the taking care of business. They’re growing up into banking online and getting job information online while maintaining the Internet’s social and entertainment pursuits they probably started in their teenage years,” Fox says.
