Abstract:
|
For legal and operational reasons, wireless phone numbers are usually excluded from RDD surveys. Wireless-only households are rapidly growing and about 6-10% of the U.S. households are wireless-only. Estimates from RDD surveys are subject to potential bias due to noncoverage of households without landline telephones. We use combined data from the 2003-2004 NHIS to compare characteristics of adults living in phoneless households with those living in wireless-only households or households with interruptions in telephone service. We select a random sample of telephone households and evaluate ratio- and propensity-based weighting methods to compensate for noncoverage of phoneless and wireless-only households using information on interruptions in landline telephone service and presence of wireless telephones. To assess bias, resulting estimates are compared with the NHIS estimates.
