About Wireless Internet Usage

An April 2009 survey by the Pew Research Center’s Internet & American Life Project shows that 56% of adult Americans have accessed the internet by wireless means, such as using a laptop, mobile device, game console, or MP3 player. The most prevalent way people get online using a wireless network is with a laptop computer; 39% of adults have done this.

The report also finds rising levels of Americans using the internet on a mobile handset. One-third of Americans (32%) have used a cell phone or Smartphone to access the internet for emailing, instant-messaging, or information-seeking. This level of mobile internet is up by one-third since December 2007, when 24% of Americans had ever used the internet on a mobile device. On the typical day, nearly one-fifth (19%) of Americans use the internet on a mobile device, up substantially from the 11% level recorded in December 2007. That’s a growth of 73% in the 16 month interval between surveys.
About the Survey

This report is based on the findings of a daily tracking survey on Americans' use of the Internet. The results in this report are based on data from telephone interviews conducted by Princeton Survey Research International between March 26 to April 19, 2009, among a sample of 2,253 adults, 18 and older. For results based on the total sample, one can say with 95% confidence that the error attributable to sampling and other random effects is plus or minus 2.4 percentage points. For results based Internet users (n=1,687), the margin of sampling error is plus or minus 2.7 percentage points. In addition to sampling error, question wording and practical difficulties in conducting telephone surveys may introduce some error or bias into the findings of opinion polls.

A combination of landline and cellular random digit dial (RDD) samples was used to represent all adults in the continental United States who have access to either a landline or cellular telephone.
