Does it take into account that more people tend to die in December, January, and February than other months? In other words, did they adjust December properly?
I agree that we can't look at the whole year until it's over, due to the irregular level of spread throughout the year.
However, it's interesting to note that during the first ten weeks of 2020, 8% fewer people died in Sweden compared to the average of 2015-2019, and 2020 had in fact the lowest number of deaths of the last six years[1] during the first ten weeks of each year.
Well, that does pose a bit of a problem comparing across years, doesn't it? I'd like to see this sort of statistical analysis done after the calendar flips over to 2021, taking into account the trend of fewer deaths per year, so we could see if there is a "COVID spike" in the data, and what the magnitude of it is.
