Child well-being in rich countries A comparative overview

"Overall, there does not appear to be a strong relationship between per capita GDP and overall child well-being. The Czech Republic is ranked higher than Austria, Slovenia higher than Canada, and Portugal higher than the United States." 

"It is international comparison that can show what is achievable in the real world, highlight strengths and weaknesses in individual countries, and demonstrate that child wellbeing is policy-susceptible. And it is international comparison that can say to politicians, press and public everywhere – ‘This is how your performance in protecting children compares with the record of other nations at a similar level of development.’"
