Mortality Improvement Analysis Subgroup

Description

This study was developed by the Mortality Improvement Analysis Subgroup of the Society of Actuaries (SOA) Research Institute’s Individual Life Experience Committee (ILEC). The purpose of this study is to present a methodology for estimating mortality improvement factors based on data from insured lives. This study is not meant to produce a proposed set of mortality improvement factors for any specific purpose; rather, actuaries can use this study as a starting point for their work on mortality improvement and add further refinements as they see fit.

There is an Excel workbook to support the results in this study. There is also a set of predictive models that were developed to help identify key variables which had a significant impact on mortality.
