Interesting how France has nearly (but not quite) as many deaths as the UK, but half the population density. The close per-capita correspondence suggests that population density isn’t broadly speaking a problem (cf. South Korea). Perhaps France really messed it up but the lack of population density has kept the toll down.
I wonder if filtering to “big cities with poorly-served concentrations of vulnerable people” is a way of making western covid19 trouble spots correspond to one another in size, density and death toll. London and New York City are massive disasters, Paris not quite as dense/bad, and Germany has no really big cities at all. But neither does Italy, especially the worst-hit parts?
