Not disputing the methodology, but our state is the nation's leader in tornadoes (by more than a factor of 2) due to Niña/Niño this year, and Chicago spent a few days this summer with the world's worst air quality due to Canadian wildfire smoke.
Obviously, "resilient" ⍯ "unaffected".
Not the leader yet and not anywhere close to "factor of 2" also the effects of el nino this year haven't even started really. It's more of a winter weather phenomenon.
Current tornado count for Illinois: 210 ( as of 8/29 ) Current record holder is Texas: 244 in 2015
However, Texas is big i don't have the math handy but I bet Illinois is well ahead in terms of tornados/square mile. ..maybe that's where your "factor of 2" comes from? Or maybe people affected since most Tornados in Texas don't affect much except maybe fences and powerlines.
