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.

    At retirement, it has become very popular for those with Defined Contribution (DC) pensions to choose drawdown rather than an annuity, but drawing a sustainable lifetime income in this way is an impossible challenge for most people. We consider a Decumulation Pathway for the typical consumer, where a small part of the DC fund is set aside for any flexible access and legacy requirements. The bulk is then used to provide a lifetime income, utilising the pooling or insuring of longevity risk.

    We continue to live in a world of global uncertainty. Survival depends on our ability to simultaneously navigate through the diverse root-causes, ranging from: the consequences of Climate Change; transitioning to Net Zero; increased inflationary pressures and supply chain issues; to self-imposed changes in regulatory requirements. CILA 2022 focuses on these challenges to ensure we continue to be informed and remain battle ready, as well as showcasing highlights of recent CMI outputs.
