Number 13: The policy-maker's guide to population ageing: Key concepts and issues
This paper recognises the steady social shift of developing countries, from youthful age structures and expansive growth, to ageing and stationary or declining populations. This shift has been brought about by the demographic transition, experienced by both developed and developing countries.
Over the past two and a half centuries, the developed world has experienced what is arguably one of humanity's greatest achievements: the demographic transition. This transition, denoted by a fall from high to low fertility and mortality, has taken place in every developed country, and is currently under way in every developing country. It has brought and continues to bring with it a number of momentous changes, most notably a shift from youthful age structures and expansive growth to ageing and stationary or declining populations.
This paper provides a useful compendium or 'tool kit' of concepts specifically related to population ageing.
