Economic inequality is today increasing in many contexts. Its consequences are multifaceted and relate to questions of justice, welfare, human well-being and health. Economic inequality also affects (directly or indirectly) society’s vulnerability to flood disasters. Research has previously shown that the ex-ante economic distribution within a country may affect the disaster outcomes. For instance, unequal societies also tend to exhibit spatial marginalization. If these marginalized areas are burdened with neglected infrastructure they also have a lower ability to divert flood water.
Our work highlights the role that economic inequality plays in explaining human flood losses, worldwide. We perform a statistical analysis using data for over a hundred countries and illustrate the importance of considering income distribution when building flood resilient societies. We also show how our results vary between different levels of economic development and discuss implications of our results on disaster research and risk reduction.
