One would think that the world’s children are only worse off in poverty-ridden Africa.

But even children in the wealthy West are also fighting poverty.

It is indeed shocking that one in five children in rich countries live in relative poverty.

A UNICEF report published on Thursday revealed this.

The report put the US and New Zealand among the world's worst performers for youth well-being.

According to the report, nearly 13% of children in those countries lack access to sufficient, safe and nutritious food.

That number rises to 20% in the US and Britain.

"Higher incomes do not automatically lead to improved outcomes for all children, and may indeed deepen inequalities," said Sarah Cook, director of the UNICEF Innocenti research office that published the study.

"Governments in all countries need to take action to ensure the gaps are reduced and progress is made," she said.

The "Report Card" took into account factors such as education, mental health, alcohol abuse, economic opportunities and the environment to rank 41 high-income countries for overall youth well-being.

Germany and the Nordic countries topped the list while Romania, Bulgaria and Chile came in at the bottom, with New Zealand and the US in 34th and 37th place respectively.
