Working paper 49: The CMI Mortality Projections Model, 'CMI_2010'
Note: The latest version of the model, 'CMI_2013', is now available here
Working paper 49 accompanies the updated version of the CMI Mortality Projections Model, 'CMI_2010', and is issued alongside the model and an updated user guide.
The structure of the 'CMI_2010' model is identical to that of the 'CMI_2009' version; however, the default parameters contained in the model have been updated to reflect the publication of England and Wales population mortality data for calendar year 2009. As a result, the default initial rates of mortality improvement have, in general, increased from those published in 'CMI_2009'. Accordingly core projections generated by the 'CMI_2010' model produce expectations of life which are generally slightly higher than those produced by 'CMI_2009' (with other parameters held constant).
This working paper illustrates the impact of incorporating data for 2009 and discusses the issues arising from the update to the model.
The previous version of the CMI Mortality Projections Model, 'CMI_2009', its user guide and an excel spreadsheet containing additional results for the parameter sensitivity tests, as described in the user guide, can be accessed alongside Working paper 41.
