Summary
Abstract: Global Multihazard Total Economic Loss Risk Deciles is a 2.5 minute grid of global multihazard

total economic loss risks. First, for each of the considered hazards (cyclones, droughts, earthquakes, floods, landslides, and

volcanoes), subnational distributions of Gross Domestic Product (GDP) are computed using a methodology developed from Sachs et al.

(2003). Where applicable, the contributions of subnational units to national GDP estimates, the contribution ratio, are determined

using data of varied origin. World Bank Development Indicators are substituted for GDP estimates of varied origin and the subnational

GDP is estimated using the fore mentioned contribution ratios. A subnational, per capita GDP is derived and a final GDP estimate per

grid cell is made based on grid cell population density. A raw, total economic loss is computed per grid cell using a regional

economic loss rate derived from EM-DAT records. To more accurately reflect the confidence surrounding the economic loss estimate, the

range of losses are classified into deciles, 10 classes of an approximately equal number of grid cells. A multihazard index is

generated by summing the top three deciles of the individual hazards. This dataset is the result of collaboration among the Columbia

University Center for Hazards and Risk Research (CHRR), International Bank for Reconstruction and Development/The World Bank, and

Columbia University Center for International Earth Science Information Network (CIESIN).


Purpose: To provide insight into the distribution and relative magnitude of global multihazard events

with regards to economic impacts.
