FEMA collects vast amounts of data on multiple aspects of emergency management — Disaster Information, Individual Assistance, Public Assistance, Hazard Mitigation, National Flood Insurance Program (NFIP), and Grants. Data sets are available for download, along with an application programming interface (API) that provides data in an easily digestible, machine readable format.
By making FEMA’s data publicly available, OpenFEMA promotes government transparency and accountability, as well as enables collaboration with community partners—such as banks, financial companies, insurance companies, mortgage and real estate companies, private sector companies, universities/academia, journalists, non-profits, federal/state/local government agencies, and citizens/individuals—to improve outcomes in support of disaster survivors.
- Release high value data sets to the public in machine-readable formats and via an application programming interface (API) in accordance with Federal Open Data directives, executive orders, and legislation.
- Institutionalize the OpenFEMA data release process throughout FEMA.
- Engage with internal and external partners to leverage FEMA's data to improve outcomes in support of disaster survivors.
OpenFEMA services are offered subject to your acceptance of the Terms and Conditions contained herein.
The Changelog identifies API feature changes as well as new, updated, and deprecated datasets.
