In 2007, the Pew Internet and American Life Project routinely added cell phone interviews to its surveys based on standard RDD land-line methodology, using questions on the breadth of internet use that have chronicled the maturation of the internet over the past eight years. The addition of cell phone interviews was designed to ensure that the internet activities of younger Americans are accurately reflected in the surveys. One of the surprising preliminary findings of these initial surveys is that the pattern of internet activities is different between those interviewed by cell phone and those interviewed by landline. These differences exist even when the differing age profiles of the two groups of respondents are taken into account. Those interviewed via cell phone are more likely to use the internet in general. But this does not mean they are simply more voracious consumers of technology. On some dimensions, buying products online, there are no differences between the groups. On other dimensions, such as use of online banking and online classifieds, the cell phone respondents are much more active online. This research raises interesting issues about the make-up and behaviors of those who are interviewed via cell phone that go beyond the straightforward search for hard-to-reach young respondents.
