Preliminary results from the January–June 2017 National Health Interview Survey (NHIS) indicate that the number of American homes with only wireless telephones continues to grow. More than one-half of American homes (52.5%) had only wireless telephones (also known as cellular telephones, cell phones, or mobile phones) during the first half of 2017—an increase of 3.2 percentage points since the first half of 2016. Nearly three-quarters of all adults aged 25-34 were living in wireless-only households; more than two-thirds (70.7%) of adults renting their homes were living in wireless-only households. This report presents the most up-to-date estimates available from the federal government concerning the size and characteristics of this population.
