7,671 migrants and refugees arrived in Europe through different land and sea routes in January 2019. More than a half (60%) of all arrivals were registered arriving through the Western Mediterranean Route.

Amiet Market, located in Abyei Administrative Area (AAA) represents one of the main transport nodes linking Sudan (SD) and South Sudan (SSD).

IOM’s Displacement Tracking Matrix (DTM) measures mixed migration flows at two transportation hubs linking Wau with Juba and Abyei Administrative Area (AAA).

 Au Burkina Faso, des Points de suivi des flux (FMP) sont installés sur plusieurs lieux de transit importants à Ouagadougou, Dori/Seytenga, Kantchari, Faramana et Yendere.

Le nombre d'individus observés aux FMPs a diminué de 38% entre le mois de décembre 2018 et de janvier 2019, passant de 

Over 16,500 children arrived in Greece, Italy, Bulgaria and Spain in the first six months of 2017, of whom more than 11,900 (72%) were unaccompanied and separated children (UASC). Arrivals in the second quarter of 2017 were more than double the first quarter (11,100 compared to 5,400).

Timely, dissaggregated data and contextualized information related to populations on the move, tranded, or seeking asylum is imperative to a well-informed, well-managed, protection sensitive and collective response across international border, governments and regions.

As part of IOM’s Ebola Virus Disease (EVD) preparedness activities, DTM operates 7 Flow Monitoring Points (FMPs) in Yambio, Yei and Morobo counties. Six additional FMPs are operated in cooperation with DTM Uganda just across the border with South Sudan (SSD).

From 01 to 31 December 2018, 42,785 movements were registered at 8 flow monitoring points, namely Mbundi and Rusumo (Muyinga province), Mukambati and Ntibitobangwa (Cankuzo province), Mungano and Kabuyenge (Ruyigi province), Kwa Elidadi and Kwa Ntunaguzi (Rutan

This report presents two types of Flow Monitoring dashboards for each country.

In January 2019, the average daily number of individuals observed at the Flow Monitoring Points increased by 2 per cent compared to the previous month.

En janvier 2019, la moyenne journalière du nombre d’individus observés aux différents points de suivi des flux a augmenté de 2 pour cent par rapport au mois précédent.

Au Sénégal, un point de suivi est installé depuis avril 2017 sur plusieurs lieux de transit importants à Tambacounda et observe plus particulièrement les mouvements quotidiens des bus de voyageurs en provenance et à destination du Mali, de la Gambie et de la Guinée.

Over the reporting period a total of 18,391 movements were observed at six (6) flow monitoring points at the border with the Democractic Republic of Congo (DRC). Inflows into Uganda were slightly higher (56%) than outflows to DRC (44%).

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.
