Child poverty is an ongoing national concern, but few are aware of its principal cause: the absence of married fathers in the home. According to the U.S. Census, the poverty rate for single parents with children in the United States in 2008 was 36.5 percent. The rate for married couples with children was 6.4 percent. Being raised in a married family reduced a child’s probability of living in poverty by about 80 percent. — Robert Rector
