Objectives The aim of the study was (I) to estimate the prevalence of Female Genital Mutilation/Cutting (FGM/C) and distribution of types of FGM/C among migrant girls and women in the Netherlands, and (II) to estimate the number of migrant girls at risk of being cut in the immediate future. Methods National population-based survey data regarding FGM/C prevalence were applied to female migrants in the Netherlands who migrated from 29 countries with available nationally representative data on FGM/C. Results As of January 1st 2018, there were 95,588 female migrants residing in the Netherlands, originating from 29 countries with available nationally representative data on FGM/C. Our findings suggest that about 41,000 women had undergone FGM/C, of which 37% had Type III (infibulation). In total 4,190 girls are estimated to be at risk of FGM/C in the next 20 years, of whom 394 were first-generation girls. Conclusion These findings show the urgency to develop appropriate strategies and policies to prevent FGM/C, to protect girls and women at risk of the practice, and to provide adequate services and support for those affected by FGM/C in the Netherlands.
