More than 230 million women and girls around the world have undergone female genital cutting, according to a new analysis by UNICEF, an increase of 30 million since the organization’s last global estimate in 2016.

While the data shows that in some countries a new generation of parents have chosen to forgo the practice, in other countries laws and campaigns against it have had no impact. In Burkina Faso, the share of girls aged 15 to 19 years who have undergone cutting has fallen to 39 percent from 82 percent over the past three decades. But in Somalia, where an estimated 99 percent of women have had their clitoris excised, the level of cutting has not changed.
