Research Insights - The Mortality Improvement Model, MIM-2021
Table of Contents
Different mortality projection methodologies are utilized by actuaries across applications and practice areas. As a result, the SOA’s Longevity Advisory Group (“Advisory Group”) developed a single framework to serve as a consistent base for practitioners in projecting mortality improvement. The Mortality Improvement Model, MIM-2021, Tools and User Guides, compose the consistent approach and are defined below.
- A report describing MIM-2021 which summarizes the evolution of MIM-2021; provides an overview of MIM-2021; presents considerations for applying mortality assumptions in the model; and outlines issues the Advisory Group is currently considering for future model enhancements.
- An Excel-based tool, MIM-2021 Application Tool, and user guide, MIM-2021 Application Tool User Guide, for practitioners to construct sets of mortality improvement rates under this framework for specific applications.
- An Excel-based tool, MIM-2021 Data Analysis Tool, and user guide, MIM-2021 Data Analysis Tool User Guide, for practitioners to analyze the historical data sets included in the MIM-2021 Application Tool.
