The world is failing impoverished kids.

Although the rate of extreme poverty is declining worldwide, children are disproportionately impacted , according to two new reports.

The number of people living in extreme poverty or on less than $1.90 a day has declined , per a report the World Bank released Sunday. In 2013, the year with the latest comprehensive data, 767 million people worldwide were living in extreme poverty, down from 881 million the previous year.

However, among the worlds poorest, children are by far the worst-hit: Kids are more than twice as likely as adults to live in extreme poverty , according to a joint World Bank and UNICEF report released Tuesday.

This report is based on data from 89 countries, representing 83 percent of the developing world. Although children make up one third of the population studied, they represent half of the extreme poor or almost 385 million kids worldwide.

Children are not only more likely to be living in extreme poverty; the effects of poverty are most damaging to children. They are the worst off of the worst off, UNICEF executive director Anthony Lake said in a release . This not only limits their futures, it drags down their societies.
