While the latest National Center for Health Statistics (NCHS) data shows us that 63 percent of American households are only or almost only reachable on their cell phones, the prevalence of people in such households varies dramatically by state. NCHS recently updated its state-by-state estimates of the prevalence of adults and children living in such households. Chart data for adults is above; children is below.

Texas has the highest prevalence of adults in wireless-only and wireless-mostly homes (75.8 percent). Close behind are Wyoming (73.9 percent), Arkansas (72.5 percent), Utah (71.7 percent), Washington, DC (71.6 percent), and Colorado (71.4 percent).

For children under 18 in such homes, Arkansas has the highest prevalence (88.8 percent). Close behind are Texas (86.2 percent), Idaho (85 percent), Mississippi (85.1 percent), Colorado (82.4 percent), South Carolina (82.1 percent), Tennessee (81.6 percent), Missouri (81.3 percent), South Dakota (80.1 percent), and Kansas (80 percent).

The growing number of households unreachable using almost any kind of telephone technology has driven our campaign to reform the Telephone Consumer Protection Act (TCPA).

These estimates are for 2015 and are based on small-area estimation methods with five years of data from the National Health Interview Survey (NHIS) and American Community Survey, with assistance from NORC at the University of Chicago.
