If that's the route you want to examine, some of the most densely populated areas of the US (Connecticut, New Jersey, Massachusetts, Maryland, DC) are still below or not far off from many of the chart-toppers in Europe.
New Jersey, 1950 dead per million
Massachusetts, 1597 dead per million
Connecticut, 1440 dead per million
Maryland, 802 dead per million
merged top US and top EU countries/states omitted: mini states like Andorra, ...
And layering on infection rates.
New Jersey, 1950 dead per million; 42,941 cases/million
Massachusetts, 1597 dead per million; 37,624 cases/million
Belgium 1,492; 51,036 cases/million
Connecticut, 1440 dead per million; 38,102 cases/million
Italy 1,003; 29,085 cases/million
Maryland, 802 dead per million; 36,083 cases/million
Spain 998; 36,689 cases/million
In regions of comparable population densities the US seems to really top out.
Not appreciably. If that's the route you want to examine, some of the most densely populated areas of the US (Connecticut, New Jersey, Massachusetts, Maryland, DC) are still below or not far off from many of the chart-toppers in Europe.
Just on a national level, recent figures for the larger European countries are proportionately way below the US.
UK, France, Italy have about 20% of the population of the US. Infections per day are not 20% of the US figures.
Which wasn't at all the case just a few weeks ago when the 7-day averages in those countries would have been the equivalent of the US posting case counts of 110K, 250K, and 150K respectively.
The situation is bad in the US, no doubt about it. But there really is not a whole lot of room for condescension and finger wagging from the European contingent about Americans taking no covid precautions when clearly our European counterparts are struggling with this as much as we are.
