Read this before you rely on it
This is a county-level figure, not a per-address probability. Kingsbury County covers about 832 square miles, so a single touch here counts the same as a single touch in a county a fraction of that size. Pre-radar-era records (before the 1990s) are also documented by NOAA as undercounting weaker tornadoes in sparsely-instrumented areas. Kingsbury County has about 5,261 residents.
