Bsking tells me the worldometers stats for states have a limitation, in that the do not account for various methods by which states compute excess deaths. Massachusetts CoVid and excess death numbers are much closer together than most (all?) other states, so they look a bit worse in the comparison. They get dinged for being more precise. Something similar just has to be happening internationally, so each country's placement lacks full precision.
Nonetheless, they are good for relative comparison purposes. Sometimes it pays to just browse around looking at the graphs over time. For those countries that are sort of like us, the months-long trends are interesting. America's graph has a different shape, a bit steadier over time. Europe had an initial spike, then nothing, and now are seeing a huge increase in cases, a more moderate increase in deaths. Spain has twice the number of new cases than it had at the height of March, deaths were near zero but are now climbing again. The UK has five times the number of cases it had in March, deaths are rising, but still not at March levels. Italy similar. France has eight times the number of new cases, deaths went to zero over the summer, now climbing alarmingly. Sweden's graph is quite different, with more consistent new cases and deaths over time, but not the recent increase in deaths. Canada's numbers are more like Europe's (though lower) but with a doubling in number of cases and a recent increase in deaths, coming up from near zero.
I won't add my guesses as to the shape of the graphs and the reasons, but one fact is pretty clear at this point. Deaths per 1000 cases are way down. Our medical teams are much better at treating this and more of those infected are surviving. Or, the virus may be weakening. Or we all may be less-infected even if we get the disease because of lowered viral load.
