PARIS — Nearly 260 million children had no access to schooling in 2018, a United Nations agency said in a report Tuesday that blamed poverty and discrimination for educational inequalities that are being exacerbated by the coronavirus outbreak.

Children from poorer communities as well as girls, the disabled, immigrants and ethnic minorities were at a distinct educational disadvantage in many countries, the UN's Paris-based education body UNESCO said.

In 2018, "258 million children and youth were entirely excluded from education, with poverty as the main obstacle to access," the report found.

This represented 17 per cent of all school-age children, most of them in south and central Asia and sub-Saharan Africa.

The disparities worsened with the arrival of the coronavirus crisis, which saw over 90 per cent of the global student population affected by school closures, the report said.

And while children from families with means could continue schooling from home using laptops, mobile phones and the internet, millions of others were cut off entirely.

"Lessons from the past – such as with Ebola – have shown that health crises can leave many behind, in particular the poorest girls, many of whom may never return to school," UNESCO's director general Audrey Azoulay wrote in a foreword. — AFP
