The one number that hasn’t really budged is the percentage of 64 year olds who have never been married. In 1960, it was 8% and in 2012, it was 7%. But the report’s authors Wendy Wang and Kim Parker say this might be changing. Each decade, the percentage of people of marriageable age who are single has grown. “When today’s young adults reach their mid-40s to mid-50s, a record high share (roughly 25%) is likely to have never been married,” they write. “This is not to say that adults in their mid-40s to mid-50s who still haven’t married will never marry, but our analysis suggests that the chance of getting married for the first time after age 54 is relatively small,” adds Parker.

Why aren’t people getting married anymore? The three main reasons people give for their singleness are that they haven’t found the right person (30%), aren’t financially stable enough (27%) and are not ready to settle down (22%). Many more young people are eschewing tying the knot, at least for a while, for shacking up. The researchers don’t see that as the new normal yet. “Cohabitation is much less common than marriage and cohabiting relationships are much less stable than marriages,” says Parker.”It’s hard to imagine marriage being replaced any time soon.”

But the Pew researchers teased out a bunch of other reasons by asking what people wanted in a partner.

The quality most women want in a husband, somewhat unromantically, is a secure job, followed very closely by similar ideas on raising kids, which was the quality most men wanted in a spouse. The problem is, the report points out, that young men are increasingly less likely to be employed. “In 1960, 93% of men ages 25 to 34 were in the labor force; by 2012 that share had fallen to 82%.”
