Reaching out to cell phone only users

[rinsd]

This came up in another thread so I went digging around.

"Whether on a landline or cellphone, people tend to screen messages and rely on caller ID numbers when deciding whether to answer the phone. Compounding the problem for surveyors is the growth of cellphone-only users, who are even harder to reach and more reluctant to take calls from unknown numbers because of the cost.

About 11.8% of adults live in households that use only cellphones, according to a recent government estimate — up from 3.5% at the end of 2003, according to the National Center for Health Statistics, which also supplied the lifestyle data on the group.

These people are generally very different from those who have landline phones, said Scott Keeter, director of survey research for the Pew Research Center.

"They're younger, they are more likely to be racial or ethnic minorities, less likely to be married, less likely to be homeowners — and all those things are associated with different political or social attitudes," Keeter said."
