En septembre 2018, la moyenne journalière du nombre d'individus observés aux différents point de suivi des flux a augmenté de 12% par rapport au mois précédent.

From mid-June until mid-August 2018, a total of 4,284 Myanmar nationals were surveyed in the province of Tak, of whom 3,765 were identified as migrant workers. The 3,765 migrant workers fell into two different migrant groups.

Results show that the daily average number of individuals observed in September at the FMPs in Nigeria increased slightly by 0.2 per cent as compared to August.

A total of 14,729 undocumented Afghans spontaneously returned
or were deported from Iran through the Milak (Nimroz) and Herat
(Islam Qala) border crossings between 14 to 20 October 2018.
21% less than in the previous week. This brings the total number

This weekly situation report covers the reporting period between 7 and 13 October 2018.

Available DTM data, from national authorities and IOM offices in Europe, shows that by the end of June 2018, a total of 58,357 migrants and refugees arrived in Europe using different land and sea routes.

In September, a total of 26,212 movements were observed at Flow Monitoring Points in Somalia, representing a significant decrease in comparison with August when 34,219 individuals were observed.

Dans le Nord du Tchad, un point de suivi a été installé depuis avril 2017 dans la ville de Kalait, suivi par l'installation de points de suivi à Faya et Zouarké en mars 2018.

Currently, 3 strategically placed FMPs remain, where DTM teams monitor incoming and outgoing flows of IDPs, identify and register drought-affected IDP families, and provide newly arriving families with IDP cards to facilitate their registration for humanitarian assistance.

According to the latest available figures from the Turkish Directorate General for Migration Management (DGMM) there are currently an estimated 3,9 million foreign nationals present in Turkey seeing international protection.

A total of 16,426 undocumented Afghans spontaneously returned
or were deported from Iran through the Milak (Nimroz) and Herat
(Islam Qala) border crossings between 07 to 13 October 2018.
21% less than in the previous week. This brings the total number

317 entries and 11 exitas were reported across all the checkpoints this week. The trend highlights a slight decrease on entries compared to last week. Few exits were recorded this week, the lowest number since March 2018.

24 entries and zero exits were recorded in Dolow IDP camps between 28 September and 4 October 2018. The number of entries decreased slightly compared to the previous week. The majority of the new arrivals cited food as their reason for displacement (60%) while the rest cited insecurity (40%).

Over the reporting period, a total number of 77 entries was recorded, which was lower than the number of entries recorded in the previous week. No exits were recorded between 28 September and 4 October 2018.

The role of IOM’s Displacement Tracking Matrix (DTM) within the humanitarian drought response is to monitor inflows of IDPs arriving in Herat, identify and register only the newly arriving IDP caseload, and report/share the information with humanitarian partners to facilitate onward registration

Este reporte presenta la información obtenida a través de las encuestas realizadas con 128 migrantes en la casa del migrante en Tecún Úman. La mayoría entre ellos (110 personas) mencionaron los Estados Unidos como su país de destino final, mientras que 16 quieren ir a Mexico.

This weekly situation report covers the reporting period between 30 September and 6 October 2018. 370 undocumented Afghan individuals returned to Afghanistan through the Torkham border crossing whilst 323 individuals used the Chaman/Spin Boldak border crossing, bringing the total number of return

IOM’s Displacement Tracking Matrix (DTM) team mobilized to respond to critical levels of internal displacement, caused by what is being described as the worst drought in Afghanistan in decades.

In July 2018, a total of 35,885 individuals were recorded in border crossing points monitored by the DTM. This represents a decrease in comparison with June 2018 when a total of 42,074 individuals were recorded.

DTM monitors population movement at 12 border crossing locations between Somalia and neighbouring countries. In November, a total of 5,383 cross-border movements were recorded, which represents a slight decrease in comparison with October (when 6,670 individuals were recorded).

December saw an increase in flows recorded in Somalia, with a total of 7,310 individuals recorded for this month (in comparison with 5,383 in November).

About is an IOM online platform designed to enhance access to Displacement Tracking Matrix (DTM) migration flow information products, including a visualization of population flows. The DTM also has a second online platform,, designed to visualize internal displacement monitored through the DTM systems; this platform facilitates a better understanding of mobility trends within a country in assessed areas.


The DTM is a system designed to track and monitor displacement and population mobility, provide critical information to decision-makers and responders during crises, and contribute to better understandings of population flows. The DTM includes four standard components – each comprising various tools and methods – that can be applied, adapted and combined as relevant in a particular context. The standard components are: (i) mobility tracking; (ii) flow monitoring; (iii) registration and (iv) surveys. Data visualized on the website is retrieved from flow monitoring exercises. 

A Flow Monitoring exercise collects information on the volume and basic characteristics of populations transiting through selected locations - referred to as Flow Monitoring Points (FMPs) – during specific observation hours. Data collected includes previous transit point(s), next destination, intended destination (when possible) and means of transportation, as well as the number, sex and nationality of migrants passing through the Flow Monitoring Point. Data is collected overtime through periodic cycles.

Once baseline data is collected through Flow Monitoring exercises. When required and as needed, Flow Monitoring Surveys (FMS) are then implemented to collect multi-layer and multi-themed data on mobile populations. FMS collect data at the individual level and include, but are not limited to, information on basic socio-economic profiles, information regarding the journey (cost, routes, modes of transport, intermediaries) and some basic data on the intentions, expectations, and perceptions of the final destination that migrants have. The findings of these surveys are used in the overall analysis presented in the IOM Flow Monitoring reports.
