The graph on this page, for example, is quite stark (US only): https://www.cdc.gov/nchs/nvss/vsrr/covid19/excess_deaths.htm
Any "excess" death calculation which doesn't account for this natural spike in death is not comprehensive whatsoever.
It's a naive calculation because it doesn't include projections we can accurately make from understanding the current state of the population. It treats the population characteristics as a black box and only uses an extrapolation of past death events as a projection. We can also accurately predict death from birth.
Did you look at the CDC graph? Do you see the very obvious wave of extra mortality, and how far it deviates from previous years? Do you see how the excess death comes in several huge waves, waves that perfectly line up with Covid-19 waves? Hell of a coincidence, don't you think?
I'd love to see this demographic analysis you cite. It must be a very sophisticated model, to perfectly predict a regular annual pattern (deviation <1%) for the past several years, abruptly followed by the wild 50% swings and chaos of the pandemic period, so accurately that you can confidently say that no one's died of Covid.
If you wanted to see that data I’m sure you’d find it. Actuaries do this kind of work.
I doubt I'll find this actuarial data, since it doesn't exist. Your proposition is ridiculous on its face - a cursory glance at the CDC graph is enough to see that. The swing in death rate is enormous and lines up perfectly with the Covid-19 waves. Actuarial data, no matter how comprehensive, doesn't say things like "40% more deaths in April". Look at the CDC graph. Look at it.
Actually, it's so ridiculous I have a hard time believing that you really believe it. Between the way you deny claiming things we can all see you claimed, and the way you've created that account just for this thread, I really think you must be trolling here.
