One factor behind the substantial growth among younger adults is their use of mobile dating apps.
About one-in-five 18- to 24-year olds (22%) now report using mobile dating apps; in 2013, only 5% reported doing so.
One-third of people who have used online dating have never actually gone on a date with someone they met on these sites.
The share of 18- to 24-year-olds who use online dating has roughly tripled from 10% in 2013 to 27% today.
Many online daters enlist their friends in an effort to put their best digital foot forward.
Some 22% of online daters have asked someone to help them create or review their profile.
