24/7 Wall St – “Americans are steadily abandoning traditional telephone landlines and exclusively using wireless devices. While 8.4% of U.S. households used only cellphones in 2005, this was true of nearly half of all American households only a decade later. The likelihood of living in a cellphone-only household varies considerably across states. New Jersey has the lowest share of adults living in wireless-only households at just 27.5%. In Idaho, the share is more than double, at 61.6% — the highest share of any state. With data from the National Center for Health Statistics, 24/7 Wall St. reviewed the share of adults in wireless-only households in every state.”
