…Young girls walk along the paths carrying even younger children on their backs and small bundles of fire wood on their heads, practising for their future roles. Up here in the now-green rainy season fields, it is very clear that women are women and girls are women in waiting. And like their mothers and grandmothers and aunts and older sisters and 140 million other girls and women worldwide, most of these young girls will be circumcised. Because no formal studies have been done, it is difficult to estimate how many females in The Gambia have been circumcised. Rough estimates run from 68% to 93%.
