State baselines by official source

Each median is calculated across every county equivalent using the same source, unit, and coverage period as its linked county profile. Category totals describe records, not severity or losses.

Administrative records

FEMA declaration distribution

OpenFEMA county-designation records show where federal disaster declarations included a county. A single declaration can designate many counties, and declaration decisions do not inventory every physical event.

How to read this state atlas

Compare like with like

Compare FEMA declarations only with FEMA declarations, and NOAA county-event records only with NOAA county-event records. Coverage periods must match.

Interpret the median carefully

A county above or below the state median has a different historical record count for the selected official source and coverage period.

Expect reporting limitations

Administrative policy and observation practices change. NOAA finalized records also lag recent event months, and zone-coded events are excluded from county totals.
