Discussing the relative risk of tornadoes vs earthquakes with a friend got me thinking about roughly how many people have been in tornadoes in their lifetime, which may be a statistic that would help put some minds at ease in tornado-prone areas, or help people better understand what they may see in various places.
I've seen various comparisons of deaths from natural disasters. They certainly change depending on the sampling period, as protection, warning, and even occurrence frequency of different disasters changes over time. (And what exactly counts as a death from each disaster) (These values seem to offer reasonable estimates for adults in the US to me.)
But I'd think it's just as meaningful to identify how much various disasters are directly dealt with.
I remember seeing an article 20 years ago from the Oklahoma Climatological Survey the average return period in some areas in central Oklahoma may be somewhere vaguely between every 1000 years to every 10000 years (obviously there are both cities and even specific points that happen to get them more often).
I can think of some ways to estimate/document such values... so what can you guys come up with?
For simplicity, let's say USA as the main goal. Bonuses for state calculations (Oklahoma in specific)... and also if you want to offer comparison to other disasters (though those estimates may be better as separate questions?)
Actual data (studies, papers, etc) would of course be best, but I'm guessing that may be very limited and also perhaps distorted by what data has been recorded... so estimates of the actual values with well described reasonings/source data would be great.
Information is power, and I can see this type of statistic being useful to folks in understanding life and the world around them.
** (I do realize that how you define "in a tornado" also likely greatly alters values. Could go by various tornado windspeeds, or just base it on tornado path dimensions given by storm surveys. As long as it is indicated/makes some sense)
