(February 2015) There are more than 3 million girls, the majority in sub-Saharan Africa, who are at risk of female genital mutilation/cutting (FGM/C) each year. Although FGM/C is most prevalent in sub-Saharan Africa, global migration patterns have increased the risk of FGM/C among women and girls living in developed countries, including the United States. On Feb. 6, 2015, International Day of Zero Tolerance to FGM/C, PRB released new data analysis showing this increased risk. In 2013, there were up to 507,000 U.S. women and girls who had undergone FGM/C or were at risk of the procedure. This figure is more than twice the number of women and girls estimated to be at risk in 2000 (228,000). The rapid increase in women and girls at risk reflects an increase in immigration to the United States, rather than an increase in the share of women and girls at risk of being cut. The analysis and PRB's package of content on FGM/C—web article, occasional paper, and shareable graphics—attracted global media attention.
