The number that matters more than frequency

Shelter and safe-room economics
Indiana's Indiana Department of Homeland Security's Residential Safe Room Program is the number that matters for a Jasper County homeowner: 75% of an approved shelter, capped at $5,000, cutting the typical $2,890-$13,280 national range to about $722.5-$8,280 net.
Power after the storm, not just shelter during it
Power loss after a tornado outbreak in Indiana often reaches homes the storm itself never touched. A battery-backup unit covers the outage without the fuel and venting a generator needs.
What Jasper County's figure does not tell you
Jasper County's figure is county-wide, not address-specific. Jasper County covers about 560 square miles, so a single touch here counts the same as a single touch in a county a fraction of that size. NOAA also documents that older records undercount weaker tornadoes from before Doppler radar became standard. Jasper County has about 33,387 residents.
