How Alabama Compares Nationally

The U.S. county-level average composite score is 12. Alabama sits at 14, which is right around the national average. 782 federal flood-related disaster declarations across 68 counties is one of the highest counts in the dataset — about 11.5 per county. Most counties have lived through multiple federally declared floods.

How Alabama's Risk Is Calculated

Every county in Alabama is scored on the same four factors that drive every county nationwide: NFIP claims density (40%), federally declared flood-disaster frequency (25%), average claim severity (20%), and year-over-year trend (15%). Source data comes from the public FEMA flood-mapping program and OpenFEMA endpoints. Detailed weighting math, plus the data's known limitations (county-level granularity, NFIP-participation bias, historical bias), is on the methodology page.

Frequently Asked Questions

What is the average flood risk score in Alabama?

Alabama's average composite flood risk score is 14 on a 0–100 scale, computed as the mean of all 68 county scores. That is roughly equal to the U.S. county-level average of 12. Score components: 40% claims density, 25% disaster frequency, 20% claim severity, 15% trend.

Which counties in Alabama have the highest flood risk?

The riskiest county in Alabama is Baldwin with a composite score of 31 (grade B). The next four — Montgomery, Jefferson, Shelby, Tuscaloosa — round out the top-five most exposed places in the state.

How many NFIP flood-insurance claims has Alabama filed?

FEMA's National Flood Insurance Program shows 993 claims on file from Alabama, with combined payouts of $31,416,446 across the dataset. 49 of the state's 68 counties have at least one NFIP claim recorded.

Are FEMA flood maps the same as your risk score?

No. The flood risk score on this page is a county-wide composite drawn from claims, disasters, severity, and trend. FEMA Flood Insurance Rate Maps (FIRMs, available at fema.gov/flood-maps) are parcel-level zone designations based on hydrologic modeling. The two answer different questions; serious decisions about insurance or building should use both, plus real-time hydrology from USGS Water Data.

When was the Alabama data last updated?

These figures were refreshed from the OpenFEMA API on 2026-05-16. FEMA itself publishes new NFIP claims on a quarterly cycle, so the data may lag actual events by up to three months.

For this entity, the underlying data on this page comes from FEMA OpenFEMA datasets including the National Flood Hazard Layer and NFIP claims. The breakdown above is the federal record; the paragraphs below add the per-entity context that makes the headline numbers usable for a real decision rather than just a data lookup.

The methodology behind every numeric value on this page is publicly documented on the FEMA OpenFEMA datasets including the National Flood Hazard Layer and NFIP claims portal and described in detail on this site’s methodology page. Refresh cadence varies by underlying series; the page surfaces the as-of date for each number so readers can trace any figure back to the source release.

For readers using this page as a decision input, the related-entity pages elsewhere on the site provide the comparison set. The most useful comparison for this entity is typically a peer within U.S. ZIPs, counties, and states with similar size, similar exposure, or similar geography — not the national-level summary alone.
