China: 650,195 disaster-driven internal displacements between 2026-09-01 and 2026-09-30 (IDMC IDU)

Disaster-driven internal displacements per month (people)

According to IDMC's Internal Displacement Updates, between 1 September and 30 September 2026 China recorded 650,195 disaster-driven internal displacements across 3 events. The alert was triggered because this monthly figure exceeded the fixed threshold of 50,000; a comparison with China's own monthly record was not made, as only 5 months of history are available against the 6 required. The largest single figure, 599,300, was reported by local authorities on 4 September under Typhoon Saudel, which affected Fujian and Hunan. Local authorities also reported 42,000 displacements from flooding in Hainan on 14 September and 193 from a landslide in Sichuan on 19 September.
