New estimates from the National Center for Health Statistics show a continued rise in wireless-only households, or households that do not have a landline telephone but did have at least one wireless telephone.
Based on early release of the National Health Interview survey, estimates from January to June of 2011 show 31.6% of households are wireless-only, up from 29.7% in the second half of 2010. The percent of children living in wireless-only households jumped from 31.8% to 35.4% in that timeframe.

This work is important for survey research. As more and more households drop their landline service it will be more expensive and difficult to capture wireless-only households in surveys (see SHADAC's issue brief on this topic for more information).
