Global Development Impact Brief #3
The Global Development Impact Brief series is designed to highlight Global Development’s work across disciplines, issues, and geographies in order to give readers insights into how we are advancing development globally in pursuit of a more equitable, sustainable, and food-secure world for all. The quarterly series is written by Global Development faculty and their partners, and is spearheaded by the Global Development Public Scholarship Committee.
The issue
Flooding is the most common and costly type of natural hazard in the United States, while the global population exposed to flooding is also growing rapidly. Globally and nationally, increasing risk is projected to drive rapid growth in the flood insurance market. A single inch of floodwater can cause as much as $25,000 in damage to a U.S. home.[i] As floods increase in frequency and severity, federal flood insurance provided through the U.S. National Flood Insurance Program (NFIP) has become a crucial tool for reducing the economic burden of floods and supporting post-disaster recovery. For example, the New York State Climate Action Council Scoping Plan highlights the goal of increasing flood insurance purchases. Insured homeowners tend to experience smaller financial losses and recover more quickly from flooding.[ii] Nonetheless, the number of homes insured through the NFIP has declined steadily since 2009.[iii] Knowing which homeowners choose to purchase flood insurance and which do not is vital to targeting efforts to increase household and neighborhood preparedness for flooding.
The approach
Our research characterizes the differences between those who have flood insurance and those who do not, investigating how their insurance choices relate to their views on flooding and flood insurance. In partnership with the Cornell Center for Conservation Social Sciences, we mailed a written questionnaire to households in three counties (Rensselaer, Rockland, and Ulster) bordering the Hudson River in New York state. In total, 1209 respondents from 48 municipalities answered questions about socioeconomic and demographic characteristics, insurance, and their views on flood risk and flood insurance. We mapped respondents’ home locations to determine whether they were within federally designated high-risk zones, termed Special Flood Hazard Areas (SFHAs). Our analyses examine flood insurance purchase and attitudes across socioeconomic status and location-based measures of risk.
