In the era of globalization, family policies and social care services are at the intersection of increasingly diverse family situations and complex welfare state environments. In Europe, child protection systems vary between countries as well as there is variation in how social services address family issues in different service areas, such as child welfare, drug and alcohol abuse, migrating families and disabilities. Similarly, there are differing approaches to the role of the state in family life and the ways different welfare states seek to balance children’s rights to protection and parents’ rights to family life. Projects in the Child and Family Welfare Cluster address the following questions: What are the nature and impact of variations in child protection systems in different welfare states? How do social work methods in family-based social work vary between welfare states? And, how do social workers across different contexts understand notions of family and how do they describe their own practices and outcomes with families?
