About the MIB Life Index

As of the January 2021 report (published in February 2021) we began reporting on industry activity using straight period over period percent changes (YTD, YOY, MOM and QOQ) based on calendar days. All historic data presented in our 2021 reports has been restated to reflect this current methodology.

The Life Index starts with all inquiries into the MIB Checking Service, including all facultatively underwritten life reinsurance activity. All inquiries from disability income, critical illness and long-term care insurance are removed from the source data. Guaranteed issue and other non-underwritten individual and group life insurance are not reflected because MIB Checking Service is not used for those market segments. Percent changes are then calculated using the average number of MIB inquiries per day for a given period.

Historical reports archived on our website reflect the methodology in place at the time of publication. As such, the annual 2020 report, and all other reports published prior, include percent changes based on a time-set benchmark with percentages based on business days. 

From January 2017 through year-end 2020 reports, the benchmark comparison (basis=100) for the MIB Life Index was January 2011. Prior to that, the benchmark comparison was January 2001.
