The Global Ageing Study Group (GASG) is a group of Japanese researchers who are interested in the ageing of the population in Africa and Asia, as well as related academic agendas such as social security, health, and welfare. Members include anthropologists, public health practitioners, physicians, demographers, health economists, geographers, and others, covering areas from East Asia, including Japan, to South Asia, and the continent of Africa.

African nations and communities have undergone a variety of social-wide changes since the start of the 21st century. The rapid population growth, the hyper-influx of people into urban areas, the increase in national intervention and social development, and information and communication infrastructure have significantly increased the penetration and establishment of modernity through globalization. Ageing populations pose the challenge of new social design at the national level with enhanced social security, health care and well-being, and the restructuring of all local systems such as labor, livelihood, production, family and households at the local and community level.

The population in Sub-Saharan Africa (SSA) has almost doubled over the past decades, with a total population of 1 billion as of 2020. One of the reasons for this population growth is the rise in survival rates due to epidemiological transition and improved health. Along with this, life expectancy, which was only in the 40s, is expected to reach the 70s in 2050 and the 80s in 2100. On the other hand, in recent years, the fertility rate around urban central areas has been declining, and it is certain that the population ratio of the elderly will increase in the latter half of this century. Currently, SSA is experiencing a situation where their birthrate is decreasing while life expectancy is increasing. These trends suggest that in the future, SSA will become a population of advanced-age individuals. That is to say, an era of an ageing population is coming.

From 2012 to the present, GASG has held a forum at the Japanese Association for International Health and has discussed ageing populations not only in Japan but also other areas, especially Asia and Africa, which have traditionally been considered unrelated to ageing. Many of the research results are published in Japanese, but we have launched this website to open our academic achievements and encourage participation in international discussion circles.
