SOLIDARITY AND IDENTITYIn the past decades several large-scale social, cultural and economic developments have occurred. Processes of economic restructuring (de-industrialization) have brought into existence new categories of unemployed people; the process of individualization is manifested in increased individual independence, a growing sense of personal rights, and -possibly -in a growing opposition between self-interest and civil virtues; the increased world-wide mobility of people, commodities, services, money and information -globalization -has far-reaching consequences for the way individual citizens are living and experiencing their lives. Contemporary society is characterized by cultural and ethnic diversity. People's social and cultural identities have become more varied. What are the consequences of these developments for the way people form social bonds and experience mutual solidarity in our society? Is there any empirical support for the widespread idea that social solidarity is declining? Which social domains -care, volunteer work, living together in old city quarters, relations between family members, neighbors, friends, etcetera -are the most vulnerable for a potential decay of solidarity? What is the role of familism and within-group solidarity among immigrant communities? Which new challenges are brought about by the multicultural society in terms of new forms of cultural expression, new (group) identities, new alliances, new institutions, new forms of formal and informal support? These and similar questions are the theme of the series Solidarity and Identity.editors of the series
