Professional pollsters are wrestling with the issue of how to do telephone surveys in an age where more and more people cannot be reached on traditional landlines. The National Center for Health Statistics has just released new data showing that 14.5% of all American adults live in households with only wireless phones. They have no landlines.
Furthermore, certain segments of the population are even more likely to be "cell only." Some 30.6% of those ages 18-24 and 19.3% of Hispanics are cell only.
The Pew Internet Project has included cell-phone samples in several recent surveys and found notable variance in technology use by those we reach in our surveys who use cell phones and those we reach on landlines. Our colleagues at our polling firm, Princeton Survey Research Associates International, reported on the results of the comparison of different types of sample at the recent conference of the American Association for Public Opinion Research.
