Study Finds More Reasons to Get and Stay Married

A new economics paper has some old-fashioned advice for people navigating the stresses of life: Find a spouse who is also your best friend.

.. A quarter of today’s young adults will have never married by 2030, which would be the highest share in modern history, according to the Pew Research Center. Yet both remaining unmarried and divorcing are more common among less-educated, lower-income people. Educated, high-income people still marry at high rates and are less likely to divorce.

Those whose lives are most difficult could benefit most from marriage, according to the economists who wrote the new paper, John Helliwell of the Vancouver School of Economics and Shawn Grover of the Canadian Department of Finance. “Marriage may be most important when there is that stress in life and when things are going wrong,” Mr. Grover said.
