The death statistics by country don't tell the whole story

For example, the U.S. deaths need to be multiplied by 3 to get the tested and non-tested deaths.

Then you have to multiply the Brazil and some other country's deaths by 12 to 16 to get an accurate count of the tested and untested deaths.

So, you might be safe in multiplying the U.S and European countries numbers by 3 to get a useful number of deaths tested and untested but most of the rest of the world the initial figures are so suspect that multiplying by 10 to 20 is a more accurate number depending upon the country for the tested AND the untested deaths from coronavirus. This is even more true in places like China and Russia where you might have to multiply by 20 to 50 to get an accurate count simply because the coronavirus in Russia and China is totally being used for Ethnic cleansing of whole groups of people there.

Only in democracies that have a large middle Class and higher standard of living is the multiply by 3 rule valid.
