Six in 10 adults in the United States go online using a wireless connection, according to the Pew Internet & American Life Project's Mobile Access 2010 report.
As of May, 59 percent of American adults accessed the Internet through a Wi-Fi or cellular connection on their laptop or cell phone. That's a slight increase from last year, when 51 percent of Americans used a wireless connection to go online.
Pew also reported that 40 percent of U.S. adults use the Internet, e-mail or instant messaging on their cell phone, up from the 32 percent of adults who did so last year.
The report found that the use of non-voice data applications on cell phones has grown dramatically over the last year. Compared with a similar point in 2009, cell phone owners are now more likely to use their mobile phones to take pictures, send text messages, access the Internet, send e-mail, record video, play music and send messages.
African-Americans and English-speaking Latinos continue to be among the most active users of the mobile Web, Pew said. Cell phone ownership is seven percentage points higher among African-Americans and Latinos than among whites and minority cell phone owners use more of their phone's features than white mobile phone users. In total, Pew found that 64 percent of African-Americans access the Internet from a laptop or mobile phone, an increase from the 57 percent who did so at a similar point in 2009.
Pew based its report on data from phone interviews conducted by Princeton Survey Research Associates International between April 29 and May 30, 2010, among a sample of 2,252 adults ages 18 and older, including 744 reached on a cell phone. The interviews were conducted in English.
