According to the National Center for Children in Poverty, 16 million children in the United States lived below the federal poverty line of $23,021 for a family of four in 2011. This amounts to about 22% of all children; when you change the criteria to low-income, the number rises to 45%. These are not all children of the unemployed or of single parents; many are in families where parents are underemployed or just unable to make it on their wages. There are only three other developed countries that have more children living in poverty than the U.S.: Mexico, Chile and Turkey. In one of the wealthiest, most advanced countries in the world, this is a national disgrace and a moral imperative for action.
