RECORDED — these are actual paid NFIP claims (a redacted census from OpenFEMA), not a model. They are the realized counterpart to the FEMA risk score above: one is what happened and got paid, the other is what a model predicts.

Scope: these are flood-insurance claims, so they undercount flooding where owners were uninsured — read this as "what NFIP paid here," not "every flood." County-level totals, not a per-property or per-address verdict. Verify a specific address and buy coverage at FloodSmart.gov; the underlying data is OpenFEMA NFIP Redacted Claims.

What these figures mean

  • RATING — the FEMA risk score, expected loss, social vulnerability, and resilience are FEMA/CDC models, not records of disasters that happened. The 0–100 scores are already national percentiles.
  • MEASURED — population is a recorded census figure.
  • COMPUTED — the county's rank within the dollar-loss distribution is our placement over the 3,232 counties.
  • CONTEXT — the note below is framing, not a measurement.

What this is — and is not

This is FEMA/CDC modeled hazard exposure for Mercer, OH and where it ranks among U.S. counties. It is not a verdict on whether Mercer is a good or bad place to live — hazard exposure is not place quality, and a county can't opt out of its geography. It is not a per-property or per-address risk assessment, not a prediction of any specific disaster, and not insurance advice. For site-specific risk use a per-property assessment; for the underlying model see FEMA National Risk Index.
