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.
