Thank you for taking an interest and all these these replies.
Maggiemaybe Yes, I have seen those coronavirus numbers but it was the up-to-date TOTAL deaths I am searching for [that is, deaths from all causes].
suziewoozie and growstuff Yes, I have just discovered the age profile numbers and, as you say, the percentage of the population over 65 in Germany is relatively high. At 21.4%, it is higher than UK, Spain and France although lower than Italy [2018 Eurostat]. The percentage for the over 80 category is 6.2% in Germany, about the same as Spain and France but higher than the UK and again, lower than Italy.
So, so I am gradually learning. I prefer to start at the ground and work up rather than read other people's analysis. I am now thinking about concentration of population as a factor sparked by the 'fact' that 25% of UK 'COVID-19' deaths have arisen in London which accounts for just 13% of the UK population. It needs more work, not least to see if Paris, a city of comparable size to London, similarly accounts for a high proportion of 'COVID-19' deaths in France. Relatively speaking, Germany does not have such a heavily populated city.
In the end, the answer may be multiple factors, some of which we don't know yet, based on clinical data. I am really only looking at the obvious ones.
