An OECD report has revealed that Israel, Turkey and Mexico have the highest rates of child poverty (in OECD countries). In these countries, over a quarter of children live in poverty. This is measured as the proportion of children living in households with an equivalised disposable income of less than half of the median income of the total population. Northern Europe has the lowest level of child poverty worldwide with the rate in Denmark 9 times lower than in Israel and Turkey.
