Survey: 11% of callers use only cellphones

Analysis of three Harris polls from late last year offered insight into U.S. consumers and their relationship to telecom, particularly the trend toward wireless substitution.
A total of more than 6,700 adults were surveyed in the online polls, and the respondents revealed that:
–81% of U.S. adults have a landline phone and 77% have a cellphone.
–About 16% use Voice over IP to make telephone calls.
–Overall, 98% of adults had phone service and the remaining 2% had no phone service at all.
The survey found that, of those users making calls, about 18% used only a landline phone, 11% used only a cellphone and 2% used only VoIP. A total of 5% relied exclusively on VoIP and cellular for calls.
The survey found that those who relied only on wireless tended to be younger, with 55% between the ages of 18 and 29 years old. Compared with the general adult population, cellphone-only users tended to skew male, better educated, less likely to be affluent, more likely to classify themselves politically as an Independent, and more liberal.
