The world has lost a fifth of its male population and one in four boys are now homeless, according to a study published on Thursday.
The UN agency UNICEF said the world lost more than 7 million males between 2015 and 2020 and nearly 9 million between 2020 and 2025, the majority of which were men between the ages of 15 and 49.
Almost one in five children are now born into poverty, the agency said, citing the World Bank and the United Nations.
It said it also noted that the majority, or nearly two-thirds, of boys now living in countries with high rates of infant mortality, such as Afghanistan, Bangladesh and Sri Lanka, were born outside their country of birth.
It added that more than one in 10 boys and more than half of girls now live in countries that have no formal education for girls.
