England & Wales population mortality updates

The CMI publishes regular analyses of mortality in England & Wales: 

  • We have published “quarterly” updates since Q4 of 2018.
  • We are publishing “pandemic” updates during the current coronavirus pandemic, which focus on COVID-19 and “excess mortality”. From week 9 of 2021 we are publishing summary versions weekly, with more detailed versions every four or five weeks.
  • We have released “beta” software that allows Authorised Users to produce their own ad hoc updates.
  • Working Paper 111 describes the methods used and contains the first update. 

Latest updates:

  • Summary pandemic – Week 28 of 2021 (published 27 July 2021)         
  • Full pandemic – Week 26 of 2021 (published 13 July 2021)       
  • Quarterly – Q2 of 2021 (published 13 July 2021)             

Next planned updates:

  • Summary pandemic – Week 29 of 2021, on 3 August 2021
  • Full pandemic – Week 30 of 2021, on 10 August 2021
  • Quarterly – Q3 of 2021, on 12 October 2021

Mortality monitor software and user guide:

The mortality monitor software allows Authorised Users to produce their own ad hoc updates whenever they wish. It produces the output that is included in the quarterly mortality monitors, but not calculations of excess mortality.

We are making the software available as a “beta” version, which is provided on an “as is” and “own risk” basis. It will need to be updated from time to time, as described in the user guide, and may stop working if the ONS changes the format of its data.

Should you encounter any errors, lack of functionality or other problems whilst using the software, please let us know by contacting projections@cmilimited.co.uk.

Although the mortality monitors are publicly available, the software is restricted to Authorised Users: employees of CMI subscribers, and researchers for non-commercial use. The CMI website has details of how to become an Authorised User, if you are not already.
