The state of Florida has had 82,397 people 34 & under test positive for the coronavirus. Of that number, 28 have died. That’s a coronavirus death rate of .00034. They’ve had 144,210 54 and under test positive. That’s a .0016 death rate.
The reality is that death rate is far too high, however, because the number of people of these ages testing positive is, at best, 1/10th of the total. So you'd have to make the numbers one tenth of this. That means of 1.4 million 34 & under the death rate would be .0000194.
