Displacement Tracking Matrix (DTM)

The Displacement Tracking Matrix (DTM) is a system to track and monitor displacement and population mobility. It is designed to regularly and systematically capture, process and disseminate information to provide a better understanding of the movements and evolving needs of mobile populations, whether on site or en route.

DTM started operating in 2004, and has been continuously refined and enhanced through years of operational experience in over 80 countries in both conflict and natural disaster settings. DTM provides decision makers with primary data and information on human mobility, both in country and at the regional and global level. It has four distinct methodological components:

  1. Mobility Tracking: Area-based assessment that regularly tracks numbers, locations and cross-sectorial needs of observed populations (stocks) to target assistance (read more...)
  2. Flow Monitoring: Tracks movements of mobile populations at key transit points (FMPs) to identify scale and direction of flows and reasons for movement (read more...)
  3. Registration: Individual and household-level information used for functional identity management in beneficiary selection, vulnerability targeting and programming
  4. Surveys: Gather specific information through sampling from the population of interest, on return intentions, displacement solutions, community perceptions and other thematic areas of interest

DTM in the East and Horn of Africa (EHoA) region is currently active in six countries (Burundi, Djibouti, Ethiopia, Somalia, South Sudan and Uganda). Flow monitoring operations in Kenya and the United Republic of Tanzania were halted at the end of 2020, with the closure of FMPs in both countries.
