Back in 1960, 72.2 percent of households included married couples; in 2012, 50.5 percent of households included married couples. Actually, these stark-appearing numbers get a little blurry the nearer that you approach. For one thing, divorce is partly responsible for the increasing number of households without a married couple. For another, there were 450,000 unmarried couples living together in 1960; there were 7.5 million in 2011. So, there are many marriages-in-all-but-name.
There appears to be some kind of reciprocal relationship between marriage and prosperity. Married people are better off financially, while people with early financial problems have trouble getting or staying married. Sharing living space and living costs allows couples to save a much higher share of their combined incomes than is possible for unmarried people. Couples often buy a house (a great investment) and save money for the education of their children. These savings compound over time.
We’re still left with a “chicken or egg” problem. Do serious people get married while frivolous people stay unmarried OR does getting married turn any bone-head into a solid citizen while economic barriers exclude willing candidates?
From one perspective, people are more or less consciously deciding to take a pass on a good thing. By one calculation, if the same share of families were married today as in 1980, “the growth in median incomes of families with children would be 44 percent higher.” In 1960 both the college educated and those with some college or less were about equally likely to marry. In 2011, 64 percent of college-educated Americans were married, while 48 percent with some college or less education were not married. Economists (other than Paul Krugman) have been explaining some of the growth in income-inequality by higher returns to more education. Thus, the decline in the marriage rate since 1970 might be taken as one of the many factors that explain the growth of income inequality.
From another perspective, however, economic difficulties for the less educated dissuade them from marriage. The decline of the old industrial base reduced the earning power of many men. At the same time, women’s liberation allowed many women to enter the labor force, often by means of a college education. As a result, marriage became less of a worthwhile investment for many women. Between 1970 and 2011 the chance that a woman in the bottom 65 percent of income earners would marry dropped by 20 percent.
So much for the fate of married couples. What about their children? In 2013, 40 percent of babies were born outside of marriage. In 2014, 27 percent of children lived in fatherless homes. In one estimate, as of 2009, 35 percent of non-Hispanic white children and 41 percent of all children did not live with married parents.
If the unmarried and no-longer-married have less in the way of economic resources than do the married, then they will be less well-positioned to help their children succeed in many ways. They have less for band camp and football camp and ballet classes. They have less for books in the home and travel. They have less for college tuition assistance. They have less time and resources to shield their children from the negative effects of the culture or—in some cases—from the pull of the streets.
Is it possible for any government program or agency to substitute for a family?
