Each year, 15 million girls are married before the age of 18 and if the current trends continue, the number of girls who marry as children will reach 1.2 billion by 2050, warns Girls Not Brides, a global organisation committed to ending child marriage.
Girls who marry as children are often not able to achieve their full potential, as they leave school early, suffer domestic violence and do not get access to proper healthcare. Some even die during pregnancy and childbirth as a result of complications because their bodies are not ready.
Child marriages affect the economies of several countries and it is worrying that some countries still allow the practice to continue.
