A new United Nations report says a lack of education for girls in developing countries may be partly to blame for a rise in poverty worldwide. The U.N. released its 2016 State of the World Population Report last week in Jordan's capital, Amman. The writers examine the well-being of 10-year-old girls as signs of success or failure of a country's development. The report says most of the world's 10-year-old children live in developing countries. In many areas, girls face barriers to good education, healthcare and safety. The report points to problems with continued gender inequality among half of the world's young population. On the day of the report’s release, a group of students sang about gender equality at a press conference in Amman. The students take classes at the city’s Princess Alia School for Girls. The report says 89 percent of the world’s 125 million 10-year-olds live in developing countries.
