# Day, SD

South Dakota · pop. 5,449 · FIPS 46037

**FEMA risk rating: Very Low** · dominant hazard: Winter Weather · modeled expected annual loss $7M/yr

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

## Where Day 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 | 27.64 | ≈ 28th pct — lower than most counties (28th percentile) (national median 50.02, n=3,144) |
| Expected annual loss | $7M | ≈ 2nd pct — among the lowest nationally (national median $15M, n=3,232) |
| Social vulnerability | 74.68 | ≈ 75th pct — higher than 75% of counties (national median 50.03, n=3,144) |
| Community resilience | 84.51 | ≈ 85th pct — higher than 85% of counties (national median 50.02, n=3,144) |

## Realized flood losses in Day (RECORDED — NFIP claims)

The National Flood Insurance Program has paid **256** flood-insurance claims totaling **$4M** in Day since 1994. The costliest year of loss was **2011** ($2M paid).

| Metric | Value |
| --- | --- |
| Total claims paid | $4,140,660 |
| Claims | 256 |
| Average claim | $16,174 |
| Largest single claim | $135,000 |
| Claims since 2000 | 120 |
| In high-risk flood zones (A/V) | 34% |

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 Day, SD and its national rank. It is **not** a verdict on whether Day 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/.
