On covid-19 death statistics

 I became aware of this published data a few weeks ago via this  Unherd  column. Since then I have checked occasionally for updated figures, and last week started to analyse the data. First I downloaded every data set from this  archive  page, going back to May 2020 (where the archived data begins, so note that Month will also include all deaths earlier in the year).

 After reading Longrider's post earlier I had a look at the ONS data he linked to and decided to present it visually.   From the data set mentioned above, here are the figures of interest: And here is it presented graphically: Finally, here is the data for last year as a pie chart: Consider this whenever you hear someone in the media going on about how women are 'unsafe in our streets'
