This web page has been set up in order to make freely available in one place all of the base mortality tables that have been produced by the CMI from data collected from UK insurance companies and officially adopted by the Actuarial Profession. While every effort has been made to ensure their accuracy, this cannot be guaranteed and neither the CMI nor the Actuarial Profession accepts any responsibility for their use in practice.

It is the responsibility of any actuary or other person using any of these mortality tables to ensure that it is appropriate for the particular purpose to which it is put.

The mortality tables are provided in Excel format and values of qx are given. For further information please refer to the original publication document for the particular table. These tables are provided as a courtesy, and the CMI cannot provide any advice on their interpretation or use.

All of these tables are contained in the software package CMI Tables Program (STP) which calculates a range of mortality and monetary functions, incorporating mortality projections where relevant. For further information on the STP, including cost, please contact stp@cmib.org.uk.
