Mobile phones have become so affordable in recent years that it's no longer uncommon to find consumers willing to ditch their landline and fly solo with a wireless account. Certainly that's the case in almost 25 percent of U.S. homes, according a recent study by the Centers for Disease Control and Prevention (CDC).
The CDC pinged some 21,375 households giving residence to more than 40,000 adults over the age of 18 and nearly 15,000 children. What they found was that 24.5 percent of those homes had at least one mobile phone and no landline account in the second half of 2009. In addition, one out of every seven U.S. homes (14.9 percent) had a landline but received all or nearly all calls on wireless telephones.
The CDC has been conducting cell phone surveys since 2003 and has seen first hand the decline of landlines in favor of mobile phones. Back in 2003, less than 5 percent of homes were mobile-phone only.
