Results presented in this section are in the form of rankings of population exposure at the
country-level. In maps, these are displayed as country-level population exposure with equal intervals
(red = highest quintile of population exposure). In tables, these are displayed as population exposure
rankings (1 = country with highest population exposure, 2 = second highest population exposure, etc.).
Note that the populations of some countries were not exposed to a given hazard event over the
1980–2000 or 1985–2003 periods of analysis, resulting in many countries tying in the ranking for
―least exposure‖. This is especially striking for cyclone exposure, a hazard that is highly concentrated
in certain regions, in which the majority of countries (136 of 228) were not exposed to a cyclone
during the 1980–2000 period of analysis. Therefore, the country rankings represented on the maps
may have the highest rank representing many countries tied for the highest rank (i.e., least exposure)
(see Tables S3–S6 in the Online Supplementary Information).
