These risk dimensions are FEMA/CDC MODELS (a rating, not records of disasters); population is a recorded census figure.

## Where St. Croix 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.

| Dimension | This county | National rank |
| --- | --- | --- |
| FEMA risk index | 64.12 | ≈ 64th pct — near the national middle (64th percentile) (national median 50.02, n=3,144) |
| Expected annual loss | $36M | ≈ 11th pct — among the lowest nationally (national median $15M, n=3,232) |
| Social vulnerability | 10.62 | ≈ 0th pct — among the lowest nationally (national median 50.03, n=3,144) |
| Community resilience | 77.39 | ≈ 77th pct — higher than 77% 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 St. Croix, WI and its national rank. It is **not** a verdict on whether St. Croix 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/.
