This volume examines the impact of globalization and individualization on social solidarity, in both a theoretical and empirical context, focusing on types of informal solidarity, such as volunteering, charitable giving, and care, as well as more formal types, such as government benefits and developmental aid. The first thorough study of international comparative data on solidarity, Sticking Together or Falling Apart concludes that, overall, solidarity is on the rise rather than declining, despite the ambiguous effects of both globalization and individualization.
