This is a ridiculous metric. On this day, we have 12% of the world’s cases, but a similar chart from a few days ago showed that out of the top 16 nations, we were 13th in cases per million, despite being the 2nd most populous nation of those 16.
India showed (when we had 10% of the world’s cases) that they had fewer than 500 confirmed cases. Either they do not know how many cases they have or there is some sort of anomaly which makes in an outlier.
If we take India out of the equation altogether, the US has 14% of the remaining world’s population and only 12% of the cases. Not so bad, according to your method of determining how good or bad things are.
