What’s Missing from National RDD Surveys? The Impact of the Growing Cell-Only Population
The number of cell-phone-only households has continued to grow — 12.8% of all households by the end of 2006, according to the National Health Interview Survey. While the noncoverage problem is currently not damaging estimates for the entire population, a study finds evidence that it does create biased estimates on certain variables for young adults, 25% of whom are cell-only.
How Serious Is Polling’s Cell-Only Problem?
The landline-less are different from regular telephone users in many of their opinions and their numbers are growing fast. Can survey researchers meet this challenge?
The World of Wireless Widens
Some 34% of internet users have logged onto the internet using a wireless connection. Users of wireless access show deeper engagement with cyberspace — at least when focusing on two basic online activities, email and news.
Cell Phone Counter-Revolution
To keep lawmakers focused on debate — and limit lobbyists’ influence — statehouses from coast to coast are restricting cell phones, instant messaging and use of those mini-computers found under the thumbs of compulsive e-mailers on the floors of state legislatures.
Cell-Only Voters Not Very Different
Political pollsters continue to cast a wary eye on the growing number of Americans who use only a cell phone and have no landline. The Pew Research Center estimates that this group now constitutes one-in-ten adults. But three Pew surveys of cell-only Americans this year have found that their absence from landline surveys is not creating a measurable bias in the bottom-line findings.
The Cell Phone Challenge to Polling
While Americans who rely solely on a cell phone for telephone service differ in their demographics from land-line subscribers, a new study finds that so far the results obtained by surveys that exclude cell-only users are not significantly affected.
Cell Phone Society
Many Americans now can’t live without them – but sometimes they can’t live with them.
