Balki Souley, a 14-year-old in Niger, lost her son in childbirth earlier this year after suffering from malnutrition for months, bleeding profusely and nearly dying.
Souley was one of the teen girls profiled in a recent story on the rising incidence of child marriage in Niger by the Washington Post’s Sudarsan Raghavan Niger has the world’s highest rate of child marriage, with one out of every two girls marrying before the age of 15.

Slate, partnering with the New America Foundation, has an interesting map showing gender disparities by country, based on metrics such as adolescent fertility, literacy rate and life expectancy. It may come as no surprise that countries in sub-Saharan Africa and the Middle East appear to be the most unequal, while Canada and Europe are the most equal:
