Age Structuring in Comparative Perspective [PDF ebook] 

This volume studies age as a basis for social organization by uniting research from the social science disciplines while implementing both cross-cultural and historical perspectives. The contributors, a distinguished interdisciplinary group of scholars, advance our understanding of age structuring by relating the changing societal level processes and individual aging experiences, and examining retirement practices, age and power in society, and cultural conceptions of age.
