The survey by the Centers for Disease Control and Prevention says 4 out of 10 homes have ditched their landlines and use only cellphones. That's twice the rate from just five years ago, although the pace seems to have slowed down in recent years.Experts believe the slight leveling off could be that people are holding onto their landlines because they're part of an Internet and cable TV package. Or, lead researcher Stephen Blumberg says, it could mean that we're hitting a ceiling for those people willing to completely abandon landlines.
The survey found that 9 percent of U.S. homes have only landlines, about 48 percent of homes have landlines and cellphones. And about 3 percent of homes have neither.
