Life insurers and life organizations sponsor many telephone surveys – and federal researchers now say land-line-only polls may miss many U.S. households.

A team of researchers led by Stephen Blumberg and Julian Luke of the National Center for Health Statistics has come to that conclusion in a “wireless substitution” paper distributed by the U.S. Centers for Disease Control and Prevention (CDC).

The researchers looked at the effects of households eliminating traditional telephone service on a major CDC survey program, the National Health Interview Survey.

The researchers looked at substitution effects on the survey conducted from January 2007 to June 2010.

The researchers concluded that about 24% of U.S. adults were living in wireless-only households.
