Latest DTM Report

About is an IOM online platform designed to enhance access to Displacement Tracking Matrix (DTM) information products on internal displacement, including a visualization of the scale of displacement monitored by IOM. A second complementary platform by DTM,, intends to visualise population flows. Each platform is designed to facilitate a better understanding of displacement and mobility trends within and between countries or regions.  

Mobility tracking aims to quantify the presence of population categories within defined locations, with a frequency that captures mobility dynamics. Its approach is highly customizable: it can be light-touch or in-depth depending on the phase and requirements of the response, and it often increases in depth and detail over successive rounds. The online platform visualises mobility tracking data collected through baseline area assessments.

Baseline area assessments provide information on the presence of internally displaced populations in a defined administrative area, their reason and date of displacement and their shelter situation. Once a baseline or a list of locations hosting displaced populations has been identified, further location and/or site assessments are conducted to gather multi-layer and multi-themed data on the displaced groups. The objective of the location/site assessments is to collect in-depth data on the living conditions and needs of populations. This may include populations in camp and camp-like settings, or populations residing within host communities and/or areas of return of the observed population of concern.

The IDP population is consistently reducing, with 50% of the originally displaced in July 2010, currently reported to be living in IDP sites.

Between the 25 October and 30 November, DTM field assessments were conducted in 1,356 IDP sites, of which 1,199 were confirmed as having IDP households living on the site.

11,250 crossing migrants were identified through 489 FMP baseline assessments from July to December 2016. During the same time, DTM analyzed 8,135 migrant surveys. The main nationalities are Niger (24%), Egypt (21%), Sudan (13%), Nigeria (9%), and Chad (6%).

As of the 31 December, the conflict in the northeastern part of Nigeria has left an estimated 1,770,444 people displaced across 6 most affected states.

Analysis of the DTM data collected across 63 IDP camps between the 13-17 December. 4,030 individuals comprising 1,033 families were recorded across these camps, 49% of these were living in improvised structures.

Situated on the international border between Cameroon and Nigeria, Kala Balge is a Local Government Area (LGA) in the conflict-affected Nigerian State of Borno. The current estimated population of IDPs is 35,295 individuals.

The dashboard is a map indicating the number of returnees per LGA. 1,099,509 returnees returned to Adamawa, Borno and Yobe States. 64,151 (5.8%) are Nigerian refugees from Chad and Cameroon. The map indicates return areas, inaccessible areas, water boundaries and state boundaries.

As of 24 March 2016 IOM has assisted 53,706 IDPs in Abyan, Aden, Al Dhale’e, Hadhramaut, Lahj, Al Mahrah, Sa’adah, Shabwah, Socotra and Taizz governorates through shelter and NFI support. 13,684 vulnerable migrants were provided with health assistance in migrant-concentrated areas and between 24
