Some of the world’s wealthiest nations, including the US, are allowing their most vulnerable children to fall behind, the UN children’s agency said yesterday.

Greece, Italy, and the US were ranked the lowest in a Unicef report which measured the gap between the average child and the most disadvantaged in terms of health, education, and material well-being in the 24 richest countries.

“When you look at their policies, there is a fragmentation of spending ... not enough is being spent on the poorest families,” Gordon Alexander of the Italy-based Unicef Innocenti Research Centre told a seminar in Helsinki, where the report was presented.

The US, for example, ranked 22nd out of 24 countries in terms of health, 19th in education, and second-to-last in material well-being.

Belgium, despite ranking a respectable sixth in health, was only 15th in material well-being and in last place for education.

“What’s surprising is that we have countries at the bottom of the list with strong education systems,” Alexander said.

Meanwhile, Finland, Denmark, The Netherlands and Switzerland all shared the top spot for having the least inequality among their children.

Alexander says the report shows that policies and political will matter a great deal in ensuring that fewer children are left behind.

“Here in Finland, we have always had, in major questions of education, a strong political consensus,” said Jouni Vaelijaervi of the Finnish Institute of Education Research.

Even so, Finland ranked only 16th in the sub-category of health, due to the poor eating habits of its youth.

Mr Alexander warns that there is still work to be done in the top countries.
