One-fifth of all adults and one-quarter of all children under 18 living in Connecticut reside in households that have wireless telephones but no landlines, according to data compiled in the National Health Statistics Report. For calendar year 2012, the most recent data available, 20.6 percent of adults age 18 and over and 25.4 percent of children under age 18 did not have a landline telephone in their home.
The report also indicates that in Connecticut, 20.6 percent of adults live in a wireless-only residence, 18.8 percent live in a mostly-wireless home, 32 percent live in a “dual-use” residence using both wireless and landline, 18.5 percent are mostly landline at home, and 9 percent have landline only.
Among children under age 18 in Connecticut, the growing dominance of mobile phones is evident, with nearly half in wireless-only (25.4 percent) or wireless-mostly (20.6 percent) households and 32.9 percent in dual-use residences. Only 11.8 percent and 8.4 percent describe their household as being landline-mostly or landline-only.
The National Health Interview Survey is the most widely cited source for data on the ownership and use of wireless telephones. It is conducted by the Centers for Disease Control and Prevention’s National Center for Health Statistics, within the U.S. Department of Health and Human Services.
The report showed “great variation in the prevalence of adults living in wireless-only households across states. Estimates for 2012 ranged from a high of 52.3 percent in Idaho to a low of 19.4 percent in New Jersey. Other states in which the prevalence of wireless-only adults was relatively high (exceeding 45 percent) were Mississippi (49.4%), Arkansas(49.0%), and Utah(46.6%).
Several other states in the northeast joined New Jersey with prevalence rates below 25 percent, including Connecticut (20.6%), Delaware (23.3%), New York (23.5%), Massachusetts (24.1%), and Rhode Island (24.9%).
Results showed a great variation in the prevalence of wireless-only children across states, ranging from a high of 63.4 percent in Mississippi to a low of 20.6 percent in New Jersey. Other states with a high prevalence of wireless-only children included Idaho (62.2%), Arkansas (59.8%), Missouri (55.2%), and South Carolina (54.5%). Other states with a low prevalence of wireless-only children included Vermont (24.5%), Connecticut (25.4%), Alaska (25.7%), and Massachusetts (26.7%).
The 2012 state-by-state data was released by the NHIS in December 2013. At the same time, the agency released composite national data for the first six months of 2013 that indicates 38.0 percent of U.S. adults lived in a household that has only mobile telephone service and no landline. As reported in the Huffington Post, their tracking shows that more than half of adults under age 35 and nearly two thirds (65.6 percent) of those ages 25 to 29 are cell-phone only.
The Pew Research Center, in a spring 2013 survey, found that ror the first time, cell phone ownership among adults has exceeded 90 percent. Cell phones are now being used by 91 percent of adults, according to the Internet & American Life Project survey conducted between April 17 and May 19 of 2,252 adults.
