About Yemen


The situation in Yemen has steadily deteriorated as a result of instability and increased fighting between multiple groups. Large scale internal displacement has been observed across the country since the conflict started in 2015. IOM Yemen’s DTM was launched the same year in an effort to better inform the humanitarian community about the location and needs of displaced populations. The DTM identifies both IDP and returnee locations and tracks displacement trends on a daily basis. The DTM also monitors key migrant arrivals and the return of Yemeni migrants mainly in locations across Yemen’s southern coastal border and northern border with the Kingdom of Saudi Arabia (KSA).

Rapid Displacement Tracking (RDT)

As part of the DTM’s mobility tracking, Rapid Displacement Tracking (RDT) primarily tracks IDP and returnee populations throughout Yemen. Information on areas of displacement and return, origins and reasons for displacement, shelter types, and priority needs are collected on a daily basis. RDT data is not representative of all displacements occurring in Yemen due to access constraints in many governorates.

Area Assessment (AA)

The Area Assessment collects stock figures on the number of IDPs, returnees, and migrants, as well as the origins, reasons for displacement, shelter types, and the situation overview at a target location. The Area Assessment data is collected through an extensive key informant network at the smallest geographical area that is operationally possible. This assessment is used to verify and update the baseline information in quarterly cycles, with field staff revisiting and updating information on all previously identified locations populated by IDP and returnee populations.

Flow Monitoring Registry (FMR)

The DTM’s Flow Monitoring Registry (FMR) monitors key third-country migrant arrivals and departures mainly in locations across Yemen’s southern coastal border as well as key Yemeni returns on the northern border with the KSA. Enumerators placed at Flow Monitoring Points (FMPs) record arrivals of migrants and returning Yemeni nationals in order to identify different patterns and types of migration, and to provide quantitative estimates to help define the population of irregular migrants entering the country. FMR is not representative of all flows in Yemen and should be understood only as indicative of the individuals recorded at FMPs during the timeframe indicated. Access constraints limit the ability to collect data at some migrant arrival points.

Multi-Cluster Location Assessment (MCLA)

In order to carry out an evidenced-based needs analysis for the Humanitarian Needs Overview (HNO), and to allow humanitarian partners to make planning decisions, the Yemen Inter-Cluster Coordination Mechanism (ICCM) proposed to carry out a Multi-Cluster Location Assessment (MCLA). This also involves the Technical Working Group (TWG) to formulate planning and implementation processes, as well as data examination and compilation. This assessment is based on the MCLA tool that has been used to assess IDP needs in previous years but has been broadened to include all key population groups that are in need of humanitarian assistance according to the previous HNO. The MCLA will provide nationwide data and evidence-based findings for the HNO to better inform the Humanitarian Response Plan (HRP) in Yemen.
