Population ageing is a well-established global demographic trend, with major socio-economic consequences. The long-term shift of the share of the population from the younger to the older ages is driven mainly by the declining levels of fertility, and also by the increases of life expectancy that are taking place almost everywhere.

Traditionally, the United Nations and most researchers have used measures and indicators that are mostly or entirely based on people’s chronological age, which provides a simple, clear and easily replicable way to measure and track various indicators of ageing. At the same time, there has been increasing recognition that the health status, type and level of activity, productivity, and other socio-economic characteristics of older persons have changed significantly over the last century, and even over the last several decades. This has led to the development of alternative concepts and measures of ageing, which provide different outlooks on the levels and trends of ageing, and a more nuanced appreciation of what ageing means in different contexts. At the frontline is the Characteristics Approach to the measurement of population ageing developed at IIASA.

At this event we will introduce the new vision to the analysis of population aging and show how this new vision have a pronounced effect on our perception of past and future trends in aging. In the framework of this new vision we will discuss the issues related to pension ages as well as the role of aging in the context of long term sustainable development.

Speaker Information

Sergei Scherbov is Deputy Program Director at the World Population Program at IIASA; a Director of Demographic Analysis of the Wittgenstein Centre for Demography and Global Human Capital, Vienna, Austria; Leader of the research group on Population Dynamics and Forecasting at the Vienna Institute of Demography, Austrian Academy of Sciences; and Director of the International Laboratory of Demography and Human Capital, Russian Presidential Academy of National Economy and Public Administration. He is also a guest professor at Chulalongkorn University in Bangkok, Thailand where he teaches advanced demographic analysis. Sergei Scherbov is invited regularly as an expert demographer by international organizations and governmental bodies. In 2012, Scherbov received a prestigious Advanced Grant from European Research Council (ERC) to study new measures of aging. His main current research interests are in population projections, new measures of aging, and analysis of aging that takes into consideration changing characteristics of people. He is an author, co-author and co-editor of several books and more than 200 articles published in professional journals including 7 articles in Science and Nature.


Warren Sanderson is an Institute Scholar at the International Institute for Applied systems Analysis (IIASA) and Emeritus Professor at Stony Brook University in New York State, USA. His research interests are in population-economic interactions. He has published in a variety of journals, including Nature, Science, Population and Development Review, Demography, Population Studies, and Population Index.
His recent research includes probabilistic population forecasting, measuring aging in ways that take life expectancy change into account, and the effects of education and other demographic changes on economic growth.


Wolfgang Lutz is Founding Director of the Wittgenstein Centre for Demography and Global Human Capital, a cooperation between IIASA (where he directs the World Population Program), the Austrian Academy of Sciences (where he is scientific director of the Vienna Institute of Demography), and the Vienna University of Economics and Business (where he is Professor of Applied Statistics).
He has widely published on international population trends with a special focus on population forecasting, population-development-environment interactions and introducing education as a standard demographic dimension in addition to age and sex. He has published over 250 scientific articles, including 11 in Science and Nature. He has won prestigious awards including the Wittgenstein Prize, two ERC Advanced Grants, the Mattei Dogan award of the IUSSP and the Mindel C. Sheps Award of PAA. He is member of the Austrian Academy of Sciences, the Leopoldina, the World Academy of Sciences (TWAS), the Finnish Society for Sciences and Letters, and the US National Academy of Sciences (NAS). Professor Lutz has been appointed by the UN Secretary-General to be one of the 15 members of the Independent Group of Scientists whose task is to produce the quadrennial Global Sustainable Development Report 2019.
