My understanding is that the annual death rate for the flue (or any other disease) takes the ANNUAL number of deaths and puts it in a rate per 100,000 individuals. Is that incorrect?

If the above is correct, then my numbers still stand, as does my prognostication, since we've really only lived with four-ish months of covid data, we still have 2/3rds of the year to go before we will know what the ANNUAL death rate is for each age segment, which could then be compared to the annual flu death rate.

To drive my point home, let's assume that magically, starting today, no one else died of covid, and we ended at 138,000 deaths or so. In this scenario, the annual death rate for covid-19 in the young adult age bracket would still be more than double the annual death rate by the flu in the young adult age bracket.
