The Displacement Tracking Matrix (DTM) system is tracking and monitoring internally displaced populations. It captures; processes and disseminates information in order to provide a better understanding of the movements and evolving needs of displaced populations; either on site (e.g. camps) or en route. It provides primary data and information at national and international level. DTM focuses on four main components: mobility tracking; flow monitoring; registration and surveys.

As of November 2016; internal displacement data is provided for 23 countries. More countries are being added to the matrix as information becomes available. The data provided covers the number of displaced people; demographics; needs and conditions in their places of refuge. It also monitors movements such as returns and secondary displacement.

The methodology adopted foresees a first stage of data collection through a network of community-level key informants and government registration data; and a second stage of validation.
