Additional Context: This information was collected by the U.N. Office for the Coordination of Humanitarian Affairs, or OCHA, from a survey conducted with 17 humanitarian actors at the regional and field level. The Displacement Tracking Matrix, or DTM, is run by the International Organization for Migration, or IOM. These reductions were noted to have impacted data collection in the Democratic Republic of the Congo, Nigeria, and Cameroon.

Devex Researcher Note: Although not listed in the source document, the U.S. enacted major cuts to its funding for the IOM — between 2024 and 2025, U.S. operational contributions declined $795 million, accounting for about 86.3% of its total funding decrease. The Global Report on Internal Displacement notes that 19 out of 26 countries where the DTM conducted assessments in 2024 experienced a decline in the number of data collection rounds in 2025. Eleven of these had no assessments conducted at all. Of the data available for 2025, only 27% was updated as of December 2025, with 52% having been collected earlier in the year and 21% already outdated.
