Recognizing and promoting the inherent dignity of people at all ages represents a foundational goal shared by societies around the world. The desire to identify meaning and value in life underpins inquiries into law and politics, religion and the arts, and it guides the resolution of ethical questions associated with scientific inquiry and resulting innovations. As medical science, public health and technology continue to advance, so lives have grown progressively longer. Increasingly, this leads to new questions regarding the kind of lives we will experience as we grow older. While advances in science and medicine increase longevity, what innovative technologies are emerging that address the changing needs faced by an aging world? Researchers, scientists, and advocates will gather in Tokyo for AGen2020 to discuss these questions and others.

Scherbov is a distinguished expert in the fields of demographic modelling, population projections, data processing and presentation, and measuring aging. For many years, Scherbov has conducted research in the field of aging and developed new measures of age and aging together with colleagues. He was principal investigator of the Euroepean Research Council funded Reassessing Ageing from a Population Perspective (Re-Ageing) project at the World Population Program at IIASA that, among other things, ascertained the extent to which advanced societies are actually aging in multiple dimensions, including health, cognitive abilities, and longevity. The results of this project were compiled in a new book entitled "Prospective longevity: A new vision of population aging" that he wrote together with Warren Sanderson and that was published in November 2019 with Harvard University Press. Scherbov is also the IIASA partners in Ageing Trajectories of Health: Longitudinal Opportunities and Synergies (ATHLOS) project, that aims to achieve a better understanding of ageing by identifying patterns of healthy ageing pathways or trajectories and their determinants, the critical points in time when changes in trajectories are produced, and to propose timely clinical and public health interventions. The new measures of aging were comprehensively presented for all countries in the world and world regions in the Aging Demographic Data Sheet 2020. this Data Sheet will be presented at this conference.

Aging in the World: Aging Demographic Datasheet 2020

Sergei Scherbov, Warren Sanderson, Stefanie Andruchowitz

In its World Aging Report 2017 and 2019 the UN Population Division includes new indicators of aging developed by the authors of this presentation at the International Institute for Applies System Analysis, that take characteristics of people into account. The World Aging Demographic Datasheet 2020 presented at this conference, includes many more newly developed indicators of aging that are not included in the UN World Aging Report. It shows population aging trends and projections until 2050 with a focus on traditional and alternative indicators of population aging for the current and future population changes across the world. Conventional measures of population aging are based solely on people’s chronological age and provide a biased picture of the extent of population aging in the future because they ignore important differences in the characteristics of people. The World Aging Datasheet 2020 shows the magnitude of that bias by comparing estimates and forecasts of population aging which adjust for differences in relevant characteristics of people with analogous measures that do not. All calculations are based on the UN World Population Prospects: The 2019 Revision. The data sheet was developed at IIASA in the framework of the ATHLOS (Ageing Trajectories of Health: Longitudinal Opportunities and Synergies) Project. ATHLOS is a five-year project funded by the European Union’s Horizon 2020 Research and Innovation Programme.
