More Americans are Googling themselves ------ and many are checking out their friends, co-workers and romantic interests, too.

In a report Sunday, the Pew Internet and American Life Project said 47 percent of U.S. adult Internet users have looked for information about themselves through Google or another search engine.

That is more than twice the 22 percent of users who did in 2002, but Pew senior research specialist Mary Madden was surprised the growth wasn't higher.

"Yes it's doubled, but many Internet users have never done this simple act of plugging their name with search engines," she said.

Americans under 50 and those with more education and income were more likely to self-Google because their jobs demand a certain online persona.

Meanwhile, Pew found that 53 percent of adult Internet users admit looking up information about someone else, not including celebrities.

Often, it's to find someone they have lost touch with. But looking up information about friends, relatives, colleagues and neighbors also was common.

Although men and women equally searched for online information about themselves, women were slightly more likely to look up information about someone they are dating.

In many cases, the search is done to find someone's contact information. But a third of those who have conducted searches on others have looked for public records, such as bankruptcies(破产) and divorce （离婚）proceedings. A similar number have searched for someone else's photo.

Few Internet users say they Google themselves regularly —— about three-quarters of self-searchers say they have done so only once or twice. And most who have done so consider what they find accurate.

Pew also found that teens were more likely than adults to restrict who can see their information at an online hangout(常去之处) like Facebook or News Corp's MySpace.
