Population ageing refers to a process whereby a population ages, i.e. the proportion of older persons in the population increases relative to that of younger persons, and the population’s median age increases. It is the result of socio-economic developments, with decreasing birth rate and increasing life expectancy. These developments have profound long-term demographic, social and economic implications. Policy makers and the society at large need to create new and supportive societal structures to deal with challenges, as well as harness potential opportunities that may arise from population ageing.
