Density in Sweden is 64 per square mile while in NY state its 421 per square mile. However, much of the population live in cities such as Stockholm that has population density 12,800 per square mile compared to 66,940 for NYC. If the dire high hospitalization and high death rate theory underlying lockdown was true, you would without lockdown expect worse than NYC death rates in Stockholm because it is very dense and we don't see that. Moreover, wouldn't number of social contacts rather than population density be a better metric here? Population density is normally a proxy for number of social contacts, but NYC is in lockdown while Sweden is not.
