Could married people soon be a minority? Just 51 percent of Americans over the age of 18 are married, according to the Pew Research Center. That’s a six percent drop from 2000. The decline is, in part, a reflection of a higher median age of marriage—older than 26 for women and nearly 29 for men. There is a socieconomic distinction, as well: Nearly two out of three college graduates have tied the knot, with less than half of people with only a high-school education can say the same.
