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:

While the demographic shift that we call population ageing started in highincome countries, low-and middle-income countries are experiencing the greatest change now (WHO, 2015). As a demographic transition, population ageing is of interest and concern to scholars, policy makers and practitioners in an array of spheres, since the rapid ageing of populations around the world means that health, labour supply and economic growth-related challenges will arise. This is why population ageing, and the globalisation of international migration, are societal trends that all of us who are involved in gerontological research, policy and practice must reckon with (Lawrence and Torres, 2016; Torres, 2019). Both trends are, of course, cause for celebration, since the fact that more of us are living to reach advanced old age is an achievement for humankind, and increased diversity can expand our imagination in more ways than we can imagine. An array of challenges are, however, posed by these trends, since they affect not only societies and the welfare systems we rely on to provide us with help in difficult times but also the social work profession in particular.
