CMI Working Paper 190

CMI Working Paper 190 was published in April 2024. The working paper presents an analysis of the mortality experience of data received by August 2023, covering the period 2015 to 2022. It is the latest in a series of such papers that are updated annually. This is the first paper to be prepared following the publication of the “S4” Series of mortality tables. 

The paper compares the mortality experience for this dataset against the unadjusted "S4" Series tables and the "S4" Series tables projected with the CMI Mortality Projections Model (CMI_2022). Results are provided for the various pensioner categories, by calendar year, and split into pension amount bands and IMD groups. We present some of the key results relative to the “S3” Series tables, for consistency with the previous paper.

The analysis shows that:

• Overall, on both a lives-weighted and amounts-weighted basis, the mortality rates experienced by pensioners are slightly heavier than the unadjusted “S4” Series tables, and the mortality rates experienced by dependants are slightly lighter than the unadjusted “S4” Series tables. 
• For most groups, mortality tended to become lighter over the period to 2019 but was heavier in 2020, 2021, and 2022.
• Mortality experience of the “IMD dataset” continues to be heavier than the experience of the “total dataset”.
• Mortality shows sharp peaks in April 2020 and January 2021, corresponding broadly to the first and second waves of the COVID-19 pandemic.  However, the increase in mortality between 2019 and 2020 appears to be lower for the SAPS dataset than in the general population.

Summary files of the data

Files used in the analysis are available below. Please note that these files have been made available on the understanding that:

• although the CMI has made reasonable attempts to validate the data, its accuracy cannot be guaranteed and the CMI accepts no liability for its use; and

There are two spreadsheets that accompany this paper:

• A spreadsheet that includes the data for the charts in the report: “CMI WP190 Chart values v01 2024-04-25.xlsx”.
• A spreadsheet that includes exposed to risk and death data by individual age and year for Pensioners and Dependants: “CMI WP190 Dataset v01 2024-04-25.xlsx”.
