This study aimed to estimate the number of girls living in the EU who were at risk of being mutilated. It developed a methodology to estimate female genital mutilation risk in the EU and carried out a pilot test in three Member States: Ireland, Portugal and Sweden. More specifically, it analysed and assessed the methodological options for estimating female genital mutilation risk, as described and applied in the existing literature and studies. The report proposes methodologies to estimate the number of girls at risk of female genital mutilation in the EU. It is intended to improve accuracy in estimating Member States. It aims to build upon and further develop research efforts to estimate the risk of FGM in the EU. Greater accuracy with respect to estimating FGM risk is important for informing appropriate policy measures for targeted prevention in the EU.
