Today, 15% of U.S. households have standard plug-in phones but almost never use them, according to new research from the National Center for Health Statistics. What's more, "One of every
four American homes (24.5 percent) had only wireless telephones (also known as cellular telephones, cellphones, or mobile phones) during the last half of 2009 -- an increase of 1.8 percentage points
since the first half of 2009," reads the report.
"In addition, one of every seven American homes (14.9 percent) had a landline yet received all or almost all calls on wireless
telephones." The report also found that 23% of adults, or 52 million people, lived in households with only wireless telephones, while nearly half of adults aged 25 to 29 lived in households with
only cellphones. Stephen Blumberg and Julian Luke of the NCHS examined data from surveys of 21,375 households that included 40,619 civilian adults and 14,984 children under the age of 18.
