Philippines: 110,439 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, between 1 and 31 July 2026 the Philippines recorded 110,439 disaster-driven internal displacements across 17 events. The alert was triggered because this monthly figure exceeded the absolute floor of 50,000 displacements; it remains below the 90th percentile of the country's own monthly record over the previous 18 months, which stands at 205,089. The largest single figure in the IDMC data, 49,132 displacements dated 17 July, is recorded under Typhoon Bavi (locally Inday) and sourced to the Department of Social Welfare and Development's DROMIC reporting.
