Against the rest of the country, that is the 49th percentile for frequency. Indiana has 92 counties in this dataset; Bartholomew County ranks 53 of them by frequency.

Paying for it, if Bartholomew County's history says you should
Nationally, storm shelters and safe rooms run $2,890-$13,280. Because Bartholomew County is in Indiana, the Indiana Department of Homeland Security's Residential Safe Room Program can cut that by 75% (capped at $5,000), to about $722.5-$8,280 net - check current funding status before counting on it.
The gap a shelter does not cover
A direct hit is not required for Bartholomew County to lose power - outbreak-wide outages across Indiana regularly reach homes and businesses well outside the actual tracks. A battery bank covers that gap without a generator's fuel and venting needs.
County-level, not address-level
Treat this as a county-wide figure, not a prediction for one address. Bartholomew County covers about 407 square miles, so a single touch here counts the same as a single touch in a county a fraction of that size. And records from before the 1990s, NOAA notes, undercount weaker tornadoes in areas with less storm-spotting coverage at the time. Bartholomew County has about 84,741 residents.
