The Symposium will be dedicated to investigating the main drivers and obstacles to longevity progress in the pre- and post-COVID eras. Contributions from demographers, epidemiologists, public health experts and researchers from related fields conducting analyses based on the cause-of-death series newly integrated into the Human Mortality Database (HMD) are particularly encouraged. The Symposium seeks to address major topics and challenges of substantive research as well as methodological and data issues.
