China: 960,265 disaster-driven internal displacements between 2026-08-01 and 2026-08-31 (IDMC IDU)

Disaster-driven internal displacements per month (people)

According to IDMC's Internal Displacement Updates, 6 disaster events accounted for 960,265 internal displacements in China between 1 and 31 August 2026. The rule compared this figure against a fixed threshold of 50,000 displacements per calendar month, as only 4 months of history were available against the 6 required for a comparison with China's own monthly record. The largest single figure in the evidence is 390,000 displacements reported by local authorities on 8 August in connection with Typhoon Dolphin, which affected 6 provinces. IDMC also records 54,000 displacements in Guangxi on 25 August linked to Typhoon Narra.
