NEW YORK (AP) — A U.S. government study finds that a majority of homes and apartments now rely solely on cellphones to communicate.

The study says that in the latter half of 2016, 50.8 percent of homes and apartments had only cellphone service. It’s the first time such households attained a majority in the survey. About 45.9 percent of households still have landline phones. The remaining households have no phone service at all.

Renters and younger adults are more likely to have just a cellphone, which researchers attribute to their mobility and comfort with newer technologies.

Nearly half of U.S. households still have a landline phone, even though it might seem redundant in the mobile-phone era.

The Centers for Disease Control and Prevention’s National Health Interview Survey doesn’t get into why people ditch or keep landlines.

Landline users reached by The Associated Press cite a range of reasons. Some people want one for emergencies, others for older relatives to call. Telemarketers can also be sent straight to the answering machine.
