Research demonstrates the important role of refugees and asylum seekers' social networks in providing both the practical and emotional support necessary to mitigate social exclusion and promote integration within receiving societies. Based on research conducted by the National Evaluation of the Children's Fund, we highlight the barriers to network building for refugee and asylum seeking children and families, and the ways in which Children's Fund strategies and practices are tackling these. Using the ‘Indicators of Integration Framework’ developed by Ager and Strang (2004), we describe the activity of Children's Fund services in relation to the concepts social bonds, social links and social bridges. Such attempts to reduce social exclusion are seen to have limited effectiveness when framed by a government policy context favouring the development of social bridges at the expense of social links and bonds.
