Population Ageing https://doi.org/10.1007/s12062-018-9225-7 George W. Leeson Springer Science+Business Media B.V., part of Springer Nature 2018 The world is ageing – both at an individual and population level – and this ageing produces challenges and opportunities for governments and citizens across the globe (Leeson and Harper, 2006, 2007a, b and c, 2008). In addition, the world is also becoming increasingly urbanised with more and more people living in urban settings. In 1950, 70% of people globally lived in rural settlements and just 30% in urban settlements. By 2014, 54% of the world’s population lived in urban settings and the urban population of the world is expected to continue to grow, so that by 2050, 66% of the world’s almost 10 billion inhabitants will be urban dwellers (United Nations 2014). As far as individual ageing is concerned, globally, life expectancies at birth have increased from 47 years in the mid-twentieth century to around 71 years today, and are expected to rise to around 78 years by the mid-twenty-first century. As far as population ageing is concerned, the proportion of the world’s population aged 60 years and over has increased from 200 million and 8% of world population in the mid-twentieth century
