West and Central Africa — Lake Chad Basin Crisis Monthly Dashboard 14 (13 November 2019)
The crisis currently affecting the Lake Chad Basin states results from a complex combination of factors, including conflict with Non-State Armed Groups, extreme poverty, underdevelopment and a changing climate, which together have triggered significant displacement of populations. As of 25 September 2019, Cameroon, Chad, Niger and Nigeria were hosting an estimated 4,645,660 affected individuals made up of Internally Displaced Persons (IDPs), Refugees (both in- and out-of-camp), Returnees (Former IDPs and Returnees from abroad) and Third Country Nationals (TCNs). 79 per cent of the affected population (representing 3,661,052 individuals) were located in Nigeria, while 10 per cent resided in Cameroon (487,691 individuals), 6 per cent in Niger (258,899 individuals) and 5 per cent in Chad (238,018 individuals).
