The tables of child poverty presented in this document are the most comprehensive estimates of child poverty across the industrialized world. Based on an analysis of the latest data from the Luxembourg Income Study of household surveys, the first figure shows the proportion of children living in poverty in 23 nations of the Organisation for Economic Cooperation and Development. It shows that child poverty rates vary from under 3% to more than 25% in the world's economically advanced nations. One in six of the rich world's children is living in poverty. In the league table of relative child poverty, the bottom four places are occupied by the United Kingdom, Italy, the United States, and Mexico. In the table of absolute child poverty, the bottom places are occupied by Spain, the Czech Republic, Hungary, and Poland. A child's chance of living in poverty is, on average, four times greater in single-parent families. The countries with the lowest child poverty rates allocate the highest proportions of the gross national product. This analysis seeks to bring together recent data from across the industrialized world in order to explore what can be learned about the causes of child poverty and the policies most likely to reduce it.
