Three out of every five low-income parents who lack insurance are married. Research indicates that earlier expansions of Medicaid eligibility for children in two-parent families encouraged marriage by helping to assure that parents could maintain their children's insurance coverage when they married. Expanding parents' insurance coverage would reduce the risk that a single parent might lose her insurance if she marries, as well as strengthen insurance coverage among low-income married families.


Insurance Coverage and Marital Status

Data from the Census Bureau's most recent annual survey of the U.S. population indicate that:


Research on the Relationship Between Marriage and Insurance Eligibility

Research by Aaron Yelowitz, now at the University of Kentucky, found that earlier efforts to expand insurance coverage in two-parent families encouraged marriage.(1) Yelowitz examined the implications of expansions in Medicaid coverage for children that occurred in the late 1980s and early 1990s. Before this time, Medicaid eligibility was primarily linked to welfare, which was mostly confined to single-parent families. That created a disincentive for marriage: if, for example, a single mother married, her children might lose insurance coverage both because she was no longer a single parent and because the family's income might rise above the state's Medicaid eligibility limits if her new husband was working. Because the Medicaid eligibility expansions for children applied to children in single- and two-parent families alike, they reduced this disincentive and, in so doing, increased the probability of marriage.

Similarly, a single parent now on Medicaid who resides in a state that has not expanded eligibility for parents risks losing her own insurance coverage if she marries a man with a modest level of earnings. In many cases, her husband might not have private health insurance or might not be able to afford the additional premiums needed to purchase dependent coverage for his wife. Almost half of workers earning $20,000 or less per year are not offered job-based health insurance, and many of those who are offered insurance cannot afford to pay the premiums.(2) Expanding Medicaid eligibility for low-income parents would reduce the risk that a single parent who marries might consequently lose health insurance and would increase insurance coverage for low-income married families.
