According to IDMC's Internal Displacement Updates, between 1 and 30 September 2026 Sudan recorded 73,112 conflict-driven internal displacements, all linked to 1 event, the countrywide non-international armed conflict, with figures reported by the IOM Displacement Tracking Matrix and dated 29 September. The alert was triggered because this figure exceeded the rule's fixed threshold of 50,000 displacements in a calendar month. Measured against Sudan's own monthly record over the previous 20 months, the figure is below the 90th percentile of 218,510.
