People used to marry in their early 20s, which meant that most dating that was done, or most courting that was done, was done with the intention of settling down right away.
And that’s not the life that young people lead anymore.
For folks who are meeting people everyday—really younger people in their early twenties—online dating is relevant, but it really becomes a powerful force for people in thin dating markets.
In a 2012 paper, I wrote about how among heterosexuals, the people who are most likely to use online dating are the middle-aged folks, because they’re the ones in the thinnest dating market.
This environment, mind you, is just like the one we see in the offline world.
