Abstract

This paper presents two measures, integration and radiality, which indicate the degree an individual is connected and reachable within a network. The measures are created using a reverse distance (geodesic) matrix, thus providing a directed closeness measure. Integration and radiality are then correlated with other centrality measures to examine the differences and similarities between each other and these other centrality measures. We then show how integration and radiality are associated with certain demographic and substantive variables. Integration and radiality provide a new index of network structure and our results show how that structure may influence behavior.
