The United States had 140 million users of wireless telephones in 2002 (ITU, 2003). That is nearly one wireless telephone for every two persons in the U.S., and 42.6% of all U.S. phones are now wireless (ITU, 2003). Moreover, wireless telephone subscribers average 490 minutes of use  per month, which is now greater than the average number of minutes per person per month logged on residential landline telephones (Yankee Group, 2003). It is perhaps not surprising, then, that many wireless telephone users have considered “cutting the cord”—substituting their residential landline telephone with a wireless telephone. Current estimates on the prevalence of persons who have “cut the cord” may be obtained from the National Health Interview Survey (NHIS). Conducted by the National Center for Health Statistics of the Centers for Disease Control and Prevention, the NHIS is an annual face-to-face survey that collects comprehensive health-related information from a large sample of households representing the civilian noninstitutionalized household population of the United States. In 2003, all NHIS respondents were asked whether “anyone in your family has a working cellular telephone.” Households were identified as wireless-only if anyone in the household had a working cellular telephone and if there were no working non-cellular telephones inside the home. Persons were identified as wireless-only if they lived in a wireless-only household. The ownership of the wireless telephones was not considered in making this assignment. This presentation will highlight the percent of households with only wireless service and the percent of persons living in households with only wireless service. Household prevalence estimates will be presented by household size, family composition, income, home ownership, and region. Person-level prevalence estimates will be presented by age, sex, race/ethnicity, education, and employment status, as well as by the household demographic categories.
