Macomb Daily – April 14, 2017
The 2012 study estimates 513,000 females under age 18 are at risk for female genital mutilation, an increase more than four times that of a 1990 estimate. Another study, conducted by The Population Reference Bureau in February 2015, estimates up to 507,000 U.S. women and girls are at risk of undergoing the procedure.
