Nation at a Glance: Wireless-Only Households
January 29, 2014
"Nation at a Glance" highlights state-specific health data on timely topics of interest. In this issue, we look at data from Wireless Substitution: State-level Estimates From the National Health Interview Survey, 2012 [PDF - 400 KB].
This report updates subnational estimates of the percentage of adults (aged 18 and over) and children (under age 18) living in households that do not have a landline telephone but have at least one wireless telephone (i.e., wireless-only households). Small area statistical modeling techniques were used to estimate the prevalence of adults and children living in households with various household telephone service types for 93 disjoint geographic areas that make up the United States. This modeling was based on 2007-2012 data from the National Health Interview Survey, 2006-2011 data from the American Community Survey, and auxiliary information on the number of listed telephone lines per capita in 2007-2012.
Click on individual states to see percentages of persons in selected states who lived in wireless-only households. "Legend" allows you to view the map for adults or children in the reporting period. Clicking "Map" returns you to the full size map.
Not Applicable (na) - Model-based estimates for Montana, South Dakota, and Wyoming are not reported because, for at least one telephone service use category, direct estimates from the National Health Information Survey were more than double or less than one-half the synthetic estimate. These differences between two components of the model-based estimates suggest that the direct estimates for these areas may be biased. Biased estimates violate a key model-based estimation assumption.
NOTE: Estimates were calculated by NORC at the University of Chicago.
