People Displaced by Natural Hazard-Induced Disasters Global Estimates 2011

This study presents global estimates for the number of people newly displaced in 2011 by disasters induced by both weather-related and geophysical hazards. Displacement related to slower-onset or gradual processes of environmental degradation such as drought and desertification and their impact on livelihoods and habitat are not included. Data for 2011 is compared with that of the previous three years, and the number of people displaced per country is considered in relation to overall population size. The estimates are based on the cross-checking of reported information from a range of sources including governments, the UN, the International Federation of Red Cross and Red Crescent Societies, the International Organisation for Migration (IOM), the International Disaster Database (EM-DAT), the Dartmouth Flood Observatory, the Asian Disaster Reduction Centre, Pacific Disaster Net, non-governmental and civil society organisations and the media.
