The latest National Health Statistics Report from the Centers for Disease Control and Prevention "presents state-level estimates of the percentage of adults and children living in households that did not have a landline telephone but did have at least one wireless telephone. National estimates for the 12-month time period from July 2009 through June 2010 indicate that 23.9% of adults and 27.5% of children were living in these wireless-only households.
"...The prevalence of wireless-only adults and children varied substantially across states. State-level estimates for July 2009–June 2010 ranged from 12.8% (Rhode Island and New Jersey) to 35.2% (Arkansas) of adults and from 12.6% (Connecticut and New Jersey) to 46.2% (Arkansas) of children. For adults, the magnitude of the increase from 2007 to 2010 was lowest in New Jersey (7.2 percentage points) and highest in Arkansas (14.5 percentage points)."
Alaska is at the top of the lowest quartile in 2009, with 19.9% or the 13th lowest rate of adults living in cellphone-only households. That's almost double the 2007 rate of 10.8%. This has implications: "Many health surveys, political polls, and other research studies are conducted using random-digit-dial (RDD) telephone surveys. Until recently, these surveys did not include wireless telephone numbers in their samples. Now, despite operational challenges, most major survey research organizations include wireless telephone numbers when conducting RDD telephone surveys. If they did not, the exclusion of households with only wireless telephones (along with the 2.0% of households that have no telephone service) could bias results."
