Yemen IDP Figures Analysis
IDMC estimates that there were over 2.5 million internally displaced people in Yemen as of 31 December 2015.*
The total number of more than 2.5 million IDPs in Yemen is unprecedented in the country’s history of displacement, and IDMC estimates that at least 85 per cent of these IDPs were displaced during 2015. The current peak in displacement is due to the renewed outbreak of conflict in Yemen between the al Houthi movement and Yemeni security forces, as well as their respective allied forces, including the Saudi-led coalition.
IDMC bases its estimate on data made available by the Task Force on Population Movements (TFPM). The TFPM operates under the Protection Cluster and is co-chaired by IOM and UNHCR. TFPM staff analyses and consolidates data on displacement collected by humanitarian partners. The humanitarian country team endorses the final estimates (TFPM 6th report, 10 December 2015).
The TFPM has faced several challenges in generating accurate displacement numbers due to the fact that the multiple data providers have used different data-collection methodologies. The total number of IDPs does not account for IDPs in areas to which the data gatherers could not access. In addition, the total IDP figure is qualified by the lack of data on secondary displacements and returns; failing to account for these processes can potentially result in inflate displacement estimates. In order to facilitate data harmonisation, the TFPM developed a common methodology amongst its partners.
The figure above does not account for displacement related to sudden- or slow-onset natural hazards. These figures are being finalised for IDMC’s annual report.
