A global transformation is taking place as the world’s population is rapidly ageing and, for the first time in history, most people can expect to live into their 60s and beyond. It is therefore understandable that one of the latest reports written by the Population Division of the United Nations’ Department of Economic and Social Affairs begins with the following statement: According to World Population Prospects 2019 (United Nations, 2019), by 2050, 1 in 6 people in the world will be over the age of 65, up from 1 in 11 in 2019. All societies in the world are in the midst of this longevity revolution – some are at its early stages and some are more advanced. But all will pass through this extraordinary transition, in which the chance of surviving to age 65 rises from less than 50 per cent – as was the case in Sweden in the 1890s – to more than 90 per cent at present in countries with the highest life expectancy. What is more, the proportion of adult life spent beyond age 65 increased from less than a fifth in the 1960s to a quarter or more in most developed countries today.
