More and more Americans are bypassing landlines and using only cellphones, a new CDC survey says. The trend encompasses people of all ages and incomes, and it's especially pronounced among the young and the poor. One-eighth (12.8%) of all households use only a cellphone—up from 3.2% in 2003—and the proportion in the 25-to-29 demographic is nearly 30%.
