Biometric Registration by IOM Nigeria’s DTM team recorded 19,437 households, corresponding to a total of 66,810 individuals in Damboa Local Government Area (LGA), covering 11 IDPs sites in Damboa Central and Nzuda Wuyaram wards and returnees in Bego ward. The overall average family size is 3.4, with 35 per cent of the families comprising of 1–2 members, 45 per cent of the families comprising of 3–4 members, 14 per cent of the families comprising 5–6 members, 5 per cent of the families comprising of 7–8 members and 2 per cent having 9–10 members. While the larger proportion, 63 per cent of the registered persons were originally from Damboa LGA, 13 per cent were from Konduga and 8 per cent from Maiduguri M.C. Other LGAs of origin included Askira/Uba, Biu, Chibok, Gombi, Gwoza, Jere, Kaga, and Mubi-North.
During the registration exercise, the enumerators collected vulnerability data to identify individuals that may require additional assistance. Out of the total population registered, about 16 per cent are people having at least one of the vulnerabilities. These figures are indicative and obtained through the interviews of the head of household in the presence of other family members.
