Every declaration on record
Major disaster (DR). The big one. Opens the full toolbox: repair money for public infrastructure, help for households, and mitigation funding to reduce the next loss.
Emergency (EM). Narrower and usually faster, for protective work before or during an incident. Capped, and rarely brings household assistance. Nearly every county has one from COVID-19.
Fire management (FM). Cost sharing to fight a wildfire as it burns. Not a disaster declaration, and it does not open recovery programs.

How these numbers are built
Drawn from FEMA's OpenFEMA Disaster Declarations Summaries, rebuilt each week. A declaration is counted here once for each designated area it names, so a single disaster covering many localities is counted in each one. For that reason these jurisdiction counts do not sum to South Dakota's statewide total. Tribal areas are counted as their own jurisdictions, separate from the counties they sit within. Totals cover complete fiscal years (Oct 1 to Sep 30). Declarations from the fiscal year still in progress are listed in the tables on this page but are not counted in the totals until the year is complete. Uses OpenFEMA data but is not endorsed by or affiliated with FEMA.
