The closet thing we have to shed light on this is excess death data. We can ask how many more people are dying that have typically died this time of year.
For example, that is what made me suspicious about Colorado. And then found the description on their weBsite that explained things. I’ll post those plots below.
From the excess death analysis, I’m not seeing anything that would suggest COVID deaths are way over-reported.
However, some important caveats
1) Data lag requires any data within last few weeks to be corrected and that correction has error (the CO plots below aren’t corrected for lag, that’s why the reported deaths get so much closer to excess deaths in the last week)
2) Fewer people are dying because they aren’t driving, performing strenuous activity, and even homicide - so excess deaths could be underestimating new deaths
3) however, people aren’t seeking treatment for certain conditions and this might be fatal and these would be excess deaths that aren’t COVID related.

Here is national analysis I did back a weeks or so ago...I need to clean it up.....but it shows COVID-associated deaths are tracking well with excess deaths (with excess deaths exceeding them so far - and that is what you want to see)
