Say I’m watching film of the 1969 World Series. What percentage of the spectators in attendance are likely to be dead today? Could someone devise a good formula that could estimate this - one that could also be applied to the 1950 World Series or an old NFL Championship Game or whatever?
You would have to get some actuarial mortality tables for the years indicated.
Then you would need some estimate of the demographics (sex and age should do) that attended those types of sporting events at that time.
Then apply a formula using the aforementioned info. and voila! You can estimate what % are no longer living.
Here’s a python script that will do some basic actuarial calculations. It uses current mortality numbers, but that’s probably close enough for a ballpark (:rimshot:) figure.
You probably want to skew your sample about 60% male and on the young side (I’m guessing 20-50 year-old guys are overrepresented at sporting events compared to the general population)
