Contemporary studies, for instance, have shown that married people are less likely to get pneumonia, have surgery, develop cancer or have heart attacks. A group of Swedish researchers has found that being married or cohabiting at midlife is associated with a lower risk for dementia. A study of two dozen causes of death in the Netherlands found that in virtually every category, ranging from violent deaths like homicide and car accidents to certain forms of cancer, the unmarried were at far higher risk than the married. For many years, studies like these have influenced both politics and policy, fueling national marriage-promotion efforts, like the Healthy Marriage Initiative of the U.S. Department of Health and Human Services. From 2006 to 2010, the program received $150 million annually to spend on projects like “divorce reduction” efforts and often cited the health benefits of marrying and staying married.
