Age, ethnicity
FGM is not invariably a rite of passage between childhood and adulthood but is often performed on much younger children. Girls are most commonly cut shortly after birth to age 15. In half the countries for which national figures were available in 2000–2010, most girls had been cut by age five. Over 80 percent (of those cut) are cut before the age of five in Nigeria, Mali, Eritrea, Ghana and Mauritania. The 1997 Demographic and Health Survey in Yemen found that 76 percent of girls had been cut within two weeks of birth. The percentage is reversed in Somalia, Egypt, Chad, and the Central African Republic, where over 80 percent (of those cut) are cut between five and 14. Just as the type of FGM is often linked to ethnicity, so is the mean age. In Kenya, for example, the Kisi cut around age 10 and the Kamba at 16.A countrys national prevalence often reflects a high sub-national prevalence among certain ethnicities, rather than a widespread practice. In Iraq, for example, FGM is found mostly among the Kurds in Erbil (58 percent prevalence within age group 15–49, as of 2011), Sulaymaniyah (54 percent) and Kirkuk (20 percent), giving the country a national prevalence of eight percent. The practice is sometimes an ethnic marker, but it may differ along national lines. For example, in the northeastern regions of Ethiopia and Kenya, which share a border with Somalia, the Somali people practise FGM at around the same rate as they do in Somalia.
In several surveys since 2006, over 50 percent of women in Mali, Guinea, Sierra Leone, Somalia, Gambia, and Egypt supported FGMs continuance, while elsewhere in Africa, Iraq, and Yemen most said it should end, although in several countries only by a narrow margin. Social obligation, poor access to information
Against the argument that women willingly choose FGM for their daughters, UNICEF calls the practice a "self-enforcing social convention" to which families feel they must conform to avoid uncut daughters facing social exclusion. Ellen Gruenbaum reported that, in Sudan in the 1970s, cut girls from an Arab ethnic group would mock uncut Zabarma girls with Ya, Ghalfa! ("Hey, unclean!"). The Zabarma girls would respond Ya, mutmura! (A mutmara was a storage pit for grain that was continually opened and closed, like an infibulated woman.) But despite throwing the insult back, the Zabarma girls would ask their mothers, "Whats the matter? Dont we have razor blades like the Arabs? "Because of poor access to information, and because circumcisers downplay the causal connection, women may not associate the health consequences with the procedure. Lala Baldé, president of a womens association in Medina Cherif, a village in Senegal, told Mackie in 1998 that when girls fell ill or died, it was attributed to evil spirits. When informed of the causal relationship between FGM and ill health, Mackie wrote, the women broke down and wept. He argued that surveys taken before and after this sharing of information would show very different levels of support for FGM.
