Online dating has jumped among adults under age 25 as well as those in their late 50s and early 60s.
The share of 18- to 24-year-olds who use online dating has roughly tripled from 10% in 2013 to 27% today.
With the use of modern technology, people can date via telephone or computer or meet in person.
However, one particularity of the human species is that pair bonds are often formed without necessarily having the intention of reproduction.
In modern times, emphasis on the institution of marriage, generally described as a male-female bond, has obscured pair bonds formed by same-sex and transsexual couples, and that many heterosexual couples also bond for life without offspring, or that often pairs that do have offspring separate.
Two thirds of online daters—66%—tell us that they have gone on a date with someone they met through a dating site or dating app.
That is a substantial increase from the 43% of online daters who had actually progressed to the date stage when we first asked this question in 2005.
These people will have dates on a regular basis, and they may or may not be having sexual relations.
