Pollsters probs with Cell-only Households
This concern is particularly relevant for young adults. According to the most recent government estimate, more than 25% of those under age 30 use only a cell phone. An analysis of young people ages 18-25 in one of the Pew polls found that the exclusion of the cell-only respondents resulted in significantly lower estimates of this age group's approval of alcohol consumption and marijuana use. Perhaps not surprisingly, excluding the cell-only respondents also yields lower estimates of technological sophistication. For example, the overall estimate for the proportion of 18-25 year olds using social networking sites is 57% when the cell-only sample is blended with the landline sample, while the estimate based only on the landline sample is 50%.
