More than half of US households now mobile-only

That figure is twice the percentage recorded in 2010 ( 26%). 

The proportion of over 65s in mobile-only households has quadrupled in the same period of time, reaching 23%, while the figure for millennials (born between 1977 and 1994 ) has grown from 47% to 71%.

After millennials, generation X (born 1965 to 1976 ) is the age group most likely to live in a mobile-only household, at 55%, while baby boomers (born 1946 to 1964 ) are the least likely, at 40%.

The figures come from GfK MRI's latest survey of the American consumer, which is based on interviews with around 24,000 US adults aged over 18.
