Does Gallup call cell phones?

Gallup includes cell phones in each national Gallup poll. Gallup has been including cell phone-only households in all national telephone Gallup polls since January 2008. Further, cell phone-only households are now as likely to fall into national Gallup polls samples as those living in traditional landline households.
Gallup and the survey research industry as a whole are exceedingly aware that increasing numbers of Americans use cell phones in addition to traditional landline phones and that more than 20% of households have only cell phones. Gallup's methodologists and survey scientists have studied, researched, conducted test polling; analyzed existing data; and examined the implications of the inclusion or exclusion of cell phones and determined that it is necessary to include cell phone numbers in survey samples despite the increased costs of doing so to ensure that the obtained samples continue to be representative of all Americans. This is particularly important given recent studies that show that people in cell phone-only households tend to be younger, are more likely to be racial and ethnic minorities, and more likely to be transient.
Gallup methodologists continue to consider and study new approaches to cell phone sampling to refine and improve upon current techniques in use.
In addition, recent annual conferences of the American Association for Public Opinion Research have included multiple scientific sessions dealing specifically with the cell phone issue. The organization and Gallup methodologists continue to consider and study new approaches to cell phone sampling to refine and improve upon current techniques in use.
