Ireland is facing a challenge with one-in-seven children here living in poverty, UNICEF has said.
A new report has found some of the world's richest countries experienced sharp rises in child poverty between 2014 and 2021.
France, Iceland, Norway, Switzerland and the UK saw increases in child poverty between 2014 and 2021.
Latvia, Lithuania, Poland and Slovenia achieved the largest reductions, according to UNICEF's latest report card.
Ireland has made progress since the global financial crisis by reducing child poverty by nearly 19%, and secured eighth position in the league table.
However, UNICEF warned that Ireland "still faces the challenge" of one-in-seven children living in poverty.
More than one-in-10 children here are experiencing prolonged poverty, lasting at least three consecutive years.
It found that, despite overall decreases in poverty by nearly 8% across 40 countries, there were still over 69 million children living in households earning less than 60% of the average national income by the end of 2021.
'Poverty risks'
The report also highlighted huge inequalities in poverty risks.
Across 38 countries with available data, children living in a lone-parent family are over three-times as likely to be living in poverty as other children.
Children with disabilities and from minority ethnic or racial backgrounds are also at higher-than-average risk.
UNICEF's Bo Viktor Nylund said child poverty can be felt for a long time.
"The impacts of poverty on children are both persistent and damaging," he said.
"For most children this means that they may grow up without enough nutritious food, clothes, school supplies, or a warm place to call home.
"It prevents the fulfilment of rights and can lead to poor physical and mental health," he added.
UNICEF has called on governments to urgently expand social protection for children, including child and family benefits, to supplement families’ household income.
It also wants to ensure all children have access to quality basic services, like childcare and free education, and more family-friendly employment policies with adequate pay.
