This research paper explored the intersection of gender and age inequality and disaster risk, at a global level and in three country case studies: Nepal, Malawi, and Dominica. The findings from the literature review highlighted incidences where women and girls have experience significant differential impacts due to inequality, in addition to situations where other genders were worse affected. The data review echoed the significant lack of disaggregated quantitative data on a global scale, with an almost complete absence of sex and age disaggregated impact data in global disaster impact databases. The country case studies also highlighted the way in which data gaps actively contribute to and reinforce exclusion. The key takeaway of the research paper is that analysis based on disaggregated quantitative impact data is insufficient on its own when attempting to meaningfully understand and take action to reduce differential impact.
