The Measuring the Cost of Disasters Act of 2025 requires the Administrator of the National Oceanic and Atmospheric Administration (NOAA) to establish and maintain a public database and webpage containing information on each billion-dollar disaster that occurs in the United States each year. The bill directs NOAA to update the database not less frequently than biannually as new information becomes available and to structure the data to include key details such as cost, disaster type, location, and date, plus additional information the Administrator deems appropriate.
The database must feature visual graphs and mapping tools that show disaster trajectories over time and the distribution of disaster types across the United States, drawing on historical features similar to those produced by the National Centers for Environmental Information from 1980 through 2024 and available online at a NOAA-hosted URL until May 9, 2025. It permits inclusion of disasters beyond the billion-dollar threshold if the Administrator determines it appropriate and requires maintenance of the previously existing disaster database for archiving and research purposes.
The bill defines a billion-dollar disaster as a storm or severe weather event with $1,000,000,000 or more in combined direct costs and market costs, as determined by the NCIE.

What This Bill Actually Does
NOAA will stand up a public database and a dedicated webpage that catalogs every billion-dollar disaster in the United States each year. The data will be public and updated at least twice a year as new information becomes available.
For each disaster, the record will include the estimated cost, the type of disaster, its location, and the date, along with other pertinent details the Administrator chooses to add. In addition to the core data, the site will offer visual graphs and maps that illustrate how disasters unfold over time and how different types of events are distributed geographically, drawing on historical features similar to the NCIE dataset from 1980 through 2024 and hosted at NOAA’s site with a reference URL that was current through May 9, 2025.
The bill further directs NOAA to use data already available to the Agency and to collaborate with federal and non-federal partners as needed, including relationships formed during the previous disaster database era (1980–2024). It also allows inclusion of disasters that are not strictly billion-dollar events if such additions aid the database’s usefulness.
Finally, NOAA must maintain and update the older NCIE disaster database on the NCIE site for archiving and research purposes, ensuring the new system complements and preserves historical records.In short, the act creates a public, standards-based mechanism for tracking disaster costs in near real time, with a clear historical through-line and visualization tools to support risk assessment, policy analysis, and resilience planning across government and industry.
The Five Things You Need to Know
The bill requires NOAA to establish and maintain a public database and webpage for billion-dollar disasters.
Updates to the database must occur not less frequently than biannually as new information becomes available.
For each disaster, the database must include cost, type, location, date, and other administrator-approved details.
The database must include graphs and maps showing disaster trajectories and type distributions, modeled after historic NCIE data (1980–2024).
A billion-dollar disaster is defined as a storm or severe weather event with $1B or more in combined direct and market costs, per NCIE methodology.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Public database and webpage mandate
NOAA must establish and maintain a public database and webpage that contains information on each billion-dollar disaster that occurs each year in the United States. The mechanism centers on making disaster-cost data accessible to policymakers, researchers, and the public to support analysis and resilience planning.
Update cadence
The Administrator must update the database and webpage not less frequently than biannually as new information becomes available. This cadence ensures the dataset remains timely and relevant for ongoing risk assessment and budgeting decisions.
Data fields and visualization
For each entry, the database must include the estimated cost, disaster type, location, date, and other information the Administrator deems appropriate. It must also provide visual graphs and mapping features showing disaster trajectories over time and the geographic distribution of disaster types, drawing on historical NCIE-style features from 1980–2024.
Data sources and collaboration
The Administrator shall use data available to NOAA and may collaborate with federal and non-federal partners as necessary, including partners with whom NOAA previously collaborated when the older database was active (1980–2024). This fosters data completeness and methodological consistency.
Inclusion of other disasters
The Administrator may include a disaster not classified as billion-dollar if inclusion would be appropriate. This provides flexibility to capture related events that enhance the database’s analytical value.
Maintenance of the existing database
NOAA must maintain and update information from the previously existing NCIE disaster database on the NCIE site for archiving and research purposes, ensuring continuity with historical records.
Definition of billion-dollar disaster
A billion-dollar disaster is defined as a storm or severe weather event that results in $1,000,000,000 or more in combined direct costs and market costs, as determined by the NCIE.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Federal emergency management agencies (for example FEMA) gain standardized data to calibrate risk models, target resources, and inform policy and grant decisions.
- State and local emergency management offices benefit from a uniform data source for planning, mitigation, and funding prioritization.
- Disaster risk modeling firms and insurers improve risk assessment practices and pricing models through access to publicly available, standardized data.
- Researchers and policy analysts gain a comprehensive dataset for trend analysis, attribution studies, and resilience research.
- Critical infrastructure operators (electric, water, transportation) can align resilience investments with transparent cost histories and risk patterns.
Who Bears the Cost
- NOAA and the Department of Commerce bear ongoing costs to build, operate, and maintain the database and its public webpage.
- Federal agencies contributing data or coordinating with NOAA incur administrative and interoperability costs.
- State and local governments may incur costs to integrate this data into planning workflows and reporting processes.
- Private sector risk-modeling firms or consultants may bear costs to adapt internal systems to leverage the new public dataset.
- Taxpayers fund NOAA’s ongoing obligations and the broader federal effort to sustain the data infrastructure.
Key Issues
The Core Tension
The central dilemma is balancing broad public accessibility and historical comparability of disaster cost data with the practical limits of data collection, standardization, and funding. Expanding the dataset to include non billion-dollar events can enhance analytical value but risks diluting focus and straining resources. Conversely, maintaining strict adherence to a fixed threshold ensures clarity but may omit meaningful context for resilience planning.
The bill creates a centralized, public repository intended to improve transparency and comparability of disaster costs across time and geography. However, it relies on the consistency and availability of data from multiple sources and on the NCIE methodology for defining market costs, which could raise questions about data comparability and methodological alignment with other datasets.
The requirement to mirror features from an earlier dataset (1980–2024) while incorporating new data could present integration challenges and potential gaps during transitions between systems. There is also a policy trade-off in allowing the inclusion of non billion-dollar disasters when appropriate, which could affect the dataset’s signal-to-noise balance and influence how stakeholders interpret trends.
Finally, the bill does not specify funding levels or sequestration-free support for NOAA, leaving the program’s long-term sustainability contingent on future appropriations.
