The provision of humanitarian assistance is highly dependent on trends and patterns of human mobility. Humanitarian actors require information on the location and composition of the affected population in order to deliver services and respond to needs in a timely and accountable manner. In Nigeria, the IOM Displacement Tracking Matrix (DTM) remains a key tool in this regard and is endorsed as the key source of data pertaining to the identification and the tracking of trends/patterns of mobility of displaced populations. 

DTM provides detailed and up-to-date information on characteristics and needs crisis-affected populations through assessments in response to rapid onset displacement, registration and profiling of displaced populations in camp and camp-like settings, flow monitoring exercises and reports, as well as the provision of detailed infrastructural information on areas of return through village assessment surveys.
