This exciting collection presents an in-depth, up-to-date analysis of the unprecedented phenomenon of increasing numbers of grandparents worldwide, co-existing and interacting for longer periods of time with their grandchildren. The book contains analyses of topics that have so far received relatively little attention, such as transnational grandparenting and gender differences in grandparenting practices. It is the only collection that brings together theory-driven research on grandparenting from a wide variety of cultural and welfare state contexts - including chapters on Europe, North America, Africa, Asia and Australia - drawing broad lines of debate rather than focusing at a country level. Building on the success of 'Contemporary grandparenting', edited by Virpi Timonen and Sarah Arber, this book further deepens our understanding of how social structures continue to shape grandparenting across a wide range of cultural and economic contexts. The book is essential reading and reference for researchers, students and policy-makers who want to understand the growing influence of grandparents in ageing families and societies across the world.
