About this research

The Flood Economics site was designed and constructed by the Economist Intelligence Unit (EIU) and commissioned by Resilience Action Partners and the Federal Emergency Management Agency (FEMA).

Through detailed community case studies and state-level mitigation data analysis, this research examines the economic as well as the broader benefits for investing in flood mitigation.


To gain a better understanding of the economic imperatives for investment in flood mitigation, the EIU undertook a research program to identify the business case for flood mitigation investment. The research spanned January-June 2016. The result is the Flood Economics website. The core of the research program is the in-depth community case studies. These case studies are comprised of insights from existing flood loss avoidance studies and additional community impacts data and analysis. In addition to the community case studies, the EIU undertook a broad analysis of projects and benefits data in the US from 1996 to 2015. The analysis covers a database of flood mitigation projects provided by FEMA of 21,411 flood-specific projects, spanning all 50 states (plus Puerto Rico).
