The conventional wisdom today is that couples should live together before getting married so that they can see if they are compatible and make sure that a marriage would “work.” As a result, over 70% of married couples lived together first, up from 5% in 1960s.
Another bit of conventional wisdom is that getting married in your 20’s is a bad idea. At that age, it is said, you are not mature enough. If you wait until your 30s, you will have a better chance of avoiding divorce and having a marriage that “works.” As a result of this belief, the median age of first marriage for women is 29 and for men 30, with college-educated couples being even older.
