Per Bertelsmann Stiftung:
Poverty and the growing gap between rich and poor is a major problem in the OECD. Of the 31 countries examined, on average, 10.8 percent of the people are poor. This means they have to live with less than half the national median household income.
U.S.: 21.6 percent of children affected by poverty
Particular concern is the phenomenon of child poverty. On average, about 12.3 percent of children live below the poverty line. Therefore, it lacks many places on the basic requirements of social justice and participation. The differences within the OECD is alarming: While in Denmark only 3.7 percent of children affected by poverty, the rate in the United States at alarming 21.6 percent (rank 28). Only Turkey, Chile and Mexico cut worse than the largest economy in the world.
