User guide for the CMI Mortality Projections Model, 'CMI_2011'

Document description

In November 2009 the CMI published a new mortality projections model, denoted 'CMI_2009'. The model was released in response to the continuation of significant year-on-year increases in life expectancy, and to concerns over the continued widespread use, albeit with modifications, of the interim cohort projections which inevitably became increasingly out-of-date.

The model has now been updated once again. The principal purpose of this annual update of the model is to incorporate 2010 population mortality data into the default core parameters for the initial rates of mortality improvement; other changes have been kept to a minimum.
