China: 4,657,267 disaster-driven internal displacements between 2026-07-01 and 2026-07-31 (IDMC IDU)

Disaster-driven internal displacements per month (people)

According to IDMC's Internal Displacement Updates, 4,657,267 disaster-driven internal displacements were recorded in China between 1 and 31 July 2026, across 7 events. The alert was triggered because this monthly figure exceeded the fixed threshold of 50,000. China has 3 months of recorded history, fewer than the 6 required for a comparison against its own monthly record. The largest single figures in the IDMC data are 2,680,000 displacements dated 11 July, recorded under Typhoon Bavi, and 900,000 dated 27 July, recorded under Typhoon Noul, both reported by local authorities.
