Relational diversity is operationalised in this chapter. A practical example to make sense of migration-driven diversity in relational terms is offered. To account for the relevance of superdiversity the analysis puts particular emphasis on migration-related markers of difference and the migration, labour market, and legal status trajectories of respondents are discussed. It is further emphasised that categorical diversity in a given population does not have to equal relational diversity. Measures of homophily and variation in the researched networks are considered to make this point. Finally the chapter shows and explains how a heatmap is a suitable visual aid in making sense of multidimensional homophily—an aid to seeing difference in similarities.
