## Where New Castle ranks among 3,232 U.S. counties

Each rank is COMPUTED — the county's modeled score placed within the national distribution. A rank within a model, not within observed disasters.

| Community resilience | 83.05 | ≈ 83rd pct — higher than 83% of counties (national median 50.02, n=3,144) |

These are **RECORDED** actual paid NFIP claims (a redacted census from OpenFEMA), not a model — the realized counterpart to the FEMA risk score above. **Scope:** flood-*insurance* claims UNDERCOUNT flooding where owners were uninsured ("what NFIP paid," not "every flood"); county-level totals, not a per-property verdict.

## What this is — and is NOT (interpretation)

This is FEMA/CDC **modeled** hazard exposure for New Castle, DE and its national rank. It is **not** a verdict on whether New Castle is a good or bad place to live (hazard exposure is not place quality), **not** a per-property or per-address assessment, **not** a prediction of any specific disaster, and **not** insurance advice. For site-specific risk use a per-property assessment; for the model see https://hazards.fema.gov/nri/.
