CITATION: Freeman, Linton C. 1978. "Centrality in Social Networks: Conceptual Clarification." Social Networks 1: 215-239.

AUTHOR_1: Linton C. Freeman
YEAR: 1978
TITLE: Centrality in Social: Conceptual Clarification
SOURCE: Journal
SOURCE_TITLE: Social Networks

SUMMARY: Discusses the state of the literature surrounding the concept of centrality in social network analysis as it stood in the late 1970s. Presents basic graph theory and terminology, followed by a formal introduction to three different conceptual approaches to measuring centrality: degree centrality, betweenness centrality, and closeness centrality. Each can be calculated in absolute or normalized fashion and a summary index at the graph level exists for each, resulting in nine total measures. The performance of these measures are compared using the 34 unique 5-actor graphs, demonstrating that while the three conceptual approaches to centrality agree at the extremes, they fail to consistently rank the intermediate graphs in the same way. The author suggests that these differences in the relative rankings imply that the three definitions of centrality are theoretically distinct and that researchers should carefully specify the dimension of the centrality concept they wish to study and relate it carefully to the measure.
