FEMA NFIP Properties with Multiple Flood Insurance Claims

The dataset covers the history of the National Flood Insurance Program, listing structures with multiple NFIP claims. It categorizes properties as Repetitive Loss or Severe Repetitive Loss and includes fields indicating current insurance status and mitigation history. The data is maintained by the Department of Homeland Security and was last updated in June 2025.

Use Cases

• Analyze the distribution of properties across Repetitive Loss and Severe Repetitive Loss categories to prioritize mitigation funding.
• Model flood risk by correlating claim history with property characteristics like current NFIP-insured status and mitigation flags.
• Track the effectiveness of mitigation efforts by examining the status of properties that have been mitigated or demolished.

Strengths

• Includes specific, defined categories of loss (Repetitive Loss, Severe Repetitive Loss) for structured analysis.
• Managed and updated by the authoritative source, the Department of Homeland Security's FEMA.
