National Flood Insurance Program Policy Transaction Records

Over 50,000,000 policy transactions from the U.S. National Flood Insurance Program, derived from the system of record and redacted to protect personally identifiable information. The dataset is updated approximately monthly and managed by the Department of Homeland Security's FEMA.

Use Cases

• Analyze policy transaction volumes and trends over time from the NFIP system of record
• Model flood insurance risk and premium patterns using redacted policyholder data
• Track policy status changes such as renewals, cancellations, and transfers processed through the NFIP
• Audit compliance with the Write Your Own program reporting standards defined in the TRRP Plan

Strengths

• Contains over 50,000,000 policy transaction records
• Data is derived from the official NFIP system of record, ensuring a direct administrative source
• Updated on an approximately monthly schedule to reflect recent transactions

Limitations

• Policyholder personally identifiable information is redacted, limiting individual-level analysis
• Data has a lag relative to the live system of record
