Displacement Tracking Matrix (DTM), Round XVII Report, June 2017


The escalation of Boko Haram violence in 2014 resulted in mass displacement around north-eastern Nigeria. To better understand the scope of displacement and assess the needs of affected populations in northeast Nigeria, the International Organization for Migration (IOM) started implementing its Displacement Tracking Matrix (DTM) program in September 2014 in collaboration with the National Emergency Management Agency (NEMA) and the State Emergency Management Agencies (SEMAs). IOM’s DTM is used in countries around the world to track displacement caused by natural disasters and conflict.


The data collected in this report comes from different DTM tools used by enumerators at various administrative levels. These administrative levels consist of Local Government Areas (LGAs), wards and displacement sites. Data is collected via interviews with key informants such as representatives of the administration, community leaders, religious leaders and humanitarian aid workers. In addition to key informant interviews and to ensure data accuracy, site and location (host community) based assessments were also conducted.

In this round of assessments, 81,383 people were interviewed. These interviews provided information on: demographic profiles, reasons for displacement, changes in the percentages of Internally Displaced Persons (IDPs) over time, origin, dwelling types, mobility and unfulfilled needs. This sample represents four per cent of the identified IDP population.
To better understand the needs of the affected population, this report includes site assessments carried out in 2,140 sites, involving a population of 1,825,321 individuals or 330,680 households. The sites included 235 camps and camp-like settings and 1,905 locations where IDPs were residing with host communities. Site assessments provide information
regarding the locations and numbers of IDPs. The 1,825,321 individuals identified represent a decrease of 59,010 persons compared to the displaced population of 1,884,331 identified in Round XVI (15 May 2017).

This report also presents an analysis of sector-wise needs and response including shelter and Non-food Items (NFI), water sanitation and hygiene (WASH), food and nutrition, health, education, livelihood, protection and communication. Lastly, this report includes assessments of returnees and their shelter conditions.

Key findings: 

From May to June 2017, the total number of identified IDPs decreased by 59, 010 (3%) individuals from last DTM Round. The number of identified people who have returned to their places of usual residence increased by 23,017 (2%) individuals from last DTM round. Survey of unmet needs showed that food remains the predominant need in majority (68%) of IDP sites.

Largest IDP populations are located in BORNO (79%), ADAMAWA (8%) and YOBE (6%). 96% of displacements were due to the insurgency

In Borno, the epicentre of the conflict, DTM continued to have partial access to 24 LGAs out of the 27 LGAs in the north-eastern state. DTM was able to assess three additional wards in this round, namely: Mboa Kura and Korongilim in Chibok and Zadawa/Hausari in Askira/Uba. Abadam, Guzamala and Marte LGAs in Borno continue to be inaccessible to the humanitarian community due to the ongoing conflict.
