Socioeconomic inequality in flood exposure and compound urban flood risk: A multistage assessment across 30,000 towns in China

Key Points

• Flood exposure is significantly affected by socioeconomic inequality in urban areas, leading to heightened vulnerability.
• In towns with lower income levels, the combined flood risks are 25% higher than in wealthier regions.
• Multistage assessment was conducted across 30,000 towns in China to analyze flood risks and exposures.
• The findings emphasize the importance of addressing socioeconomic factors to mitigate urban flood risks effectively.
