Truth #1: The magnitude of cohabitation rather than marriage isn’t what we think it is.
When I ask people what percentage of 25- to 34-year-old, living-together couples are unmarried, most guess in the 50-75% range. In other words, we think most young couples who live together are shacking up rather than making a marriage commitment.
The actual ratio is 26%. A full 74% of those who live together at that age are married. Puts a different spin on things, doesn’t it?
