This chapter focuses on the potential of using the concentric circles (CC) method. The CC method is an interview-based data collection procedure that allows researchers to co-construct personal networks with respondents. Specifically, respondents map their network in a dynamic and visual way on concentric circles, allowing researchers to easily capture data on the ego, alter, alter-by-alter, and tie levels. The CC method also facilitates the simultaneous collection of quantitative and qualitative network data. Drawing on concrete examples, we present a practical layout for both researchers and practitioners on how the CC method can be adopted. We also demonstrate how the CC method can be used in various mixed method designs and for various research purposes: to gather insight into the quality of ties, to deepen understanding of network dynamics, to build network visualizations, to gain insight into network agency, and to design network interventions.
