Continuous Mortality Investigation

The Continuous Mortality Investigation (CMI) carries out research into mortality and morbidity experience and produces practical tools that are widely used by actuaries

The CMI’s work is focused on five investigations

Four of these consider areas of base mortality and morbidity, analysing data supplied by UK life assurance companies and actuarial consultancies; these investigations cover:

  • Annuitant mortality
  • Assurances (critical illness and mortality)
  • Income protection, and
  • Self-administered pension scheme (SAPS) mortality.

Each investigation analyses the experience observed in subsets of the aggregated data and periodically produces mortality and morbidity tables.

The fifth investigation covers mortality projections and considers future changes in mortality experience, an area of great importance to actuaries.  

The CMI is funded by subscriptions

The subscribers have access to all the outputs we produce; these are also made available to academics and researchers for non-commercial use. Historically, most of CMI’s work was published more widely and these publications remain freely-available on the website.

    Part of the 'Finance in the Public Interest 2022' webinar series. If it was ever okay to consider your business in isolation from its surroundings, today it most definitely is not. Thinking about business within its surrounding system is now a necessity. The question we seek to discuss is: How should we prescribe the boundaries in which we consider problems to enable us to create better products and more resilient companies and systems?

    What will happen to DC pension savers who see life annuities as poor VFM but still want an income for life?  Pooled annuity funds could offer them a decent lifetime income while reducing significantly the complex choices and risk inherent in income drawdown.  They could be the next generation of CDC pension schemes, slotting into the existing DC framework as a post-retirement option.
