Average expected number of displacements per year – for sudden-onset hazards:
IDMC’s estimates of the total number of IDPs in Niger and the number of new displacements in 2018 are primarily based on data reported by the government, obtained through surveys conducted by local authorities. The data covers the south-eastern region of Diffa, which borders Lake Chad and has been severely affected by the Boko Haram insurgency. IDMC’s estimates also reflect information obtained from the protection cluster about displacement caused by attacks in Tillabéri and Tahoua as a result of spill-over violence from Mali. IDMC’s estimate of the total number of IDPs also accounts for Nigerien refugees whom the government reported as having returned to displacement camps in the country.
