Do the Health Benefits of Marriage Depend on the Likelihood of Marriage?

Abstract

Marriage promotion initiatives presume substantial health benefits of marriage. Current literature, however, has provided inconsistent results on whether these benefits would be shared by people unlikely to marry. We investigate whether the physical and mental health benefits of marriage depend on the likelihood of marriage. Whereas prior studies have compared health benefits of marriage across a single predictor of marriage chances, we define the likelihood of marriage as a composite of demographic, economic, and health characteristics. Using the National Longitudinal Survey of Youth 1979, we find that married adults are only modestly healthier than unmarried adults in both physical and mental dimensions. People with a higher likelihood of marriage generally do not reap greater health benefits from marriage than their counterparts. The only exception is that continuous marriage is more strongly associated with improved mental health among men who are more likely to be married.
