MapPoint 2004 (maybe 2002 as well, I haven't looked) has a "Tornado Index" in the supplied information. This will give everyone an idea. When I looked at it, it looked like it was based on insurance claims - there were a lot of "hotspots" on cities...
It may be incomplete - the "Earthquake Index" data excludes Alaska - even though it is the most seismically active part of the US!
re. Texas: I lived in Houston for 3 years and never saw one. I don't even know where the local sirens were. Flooded by two Tropical Storms though (one was the day I left for good).
Up here in the Dallas area, we get the sirens a few times at about this time of year (none yet). Two years ago we had one pass the top end of ths treet, but it wasn't touching down at the time. Over in Arlington it took out a couple of houses, and the Dallas Morning News had a good shot of it with the University of Dallas and Texas Stadium (both are within a mile or so of where I live).
Oklahoma seems to get a lot more than us, and Houston quite a few less...
