Notes: Some 41% of US households were wireless-only during the second half of 2013, per the study, with this representing a 2.8% point increase from the year-earlier period. Close to 2 in 3 adults aged 25-29 live in wireless-only households, the highest rate of any age bracket. The results also indicate that men are slightly more likely than women to live in wireless-only households, while Hispanic adults (53.1%) are far more likely than non-Hispanic white (35.1%) or non-Hispanic black (42.1%) adults to live in wireless-only households. A majority 56% of households have landlines (with or without wireless), while 2.5% are phoneless.
