You also have to adjust for the people who are already sick but haven't died yet. That would likely get you somewhere between 1 and 1.5%. So for herd immunity in the US at 200,000,000 recovered, that would be 2 to 3 million. That's consistent with earlier projections.

one problem with all these projections is that they all assume everyone is the same and that it is just a matter of chance. Not true in the least bit. those most susceptible get the disease first, those most sensitive die first - I believe the ratios will not stay the same, but continuously tick downwards

  On the other part, those who are more vulnerable are more aware, and are implementing more measures in their daily living, hence they are not getting infected as much, currently. Hope it stays that way.

    Not sure that makes any difference. Not only are death rates sharply higher in older people, but their infection rates relative to the population are also higher as well.

      Without better testing, you have no way of knowing whether older people have higher infection rates. Infection rates depend on far more variables than age. Witness what's happening on the Teddy Roosevelt.
