Social network metric	Definition	Possible range	Value
Size	The number of nodes (eg, users) in the network	N/Aa	505,047
Diameter	The largest geodesic distance, which is the shortest distance from one node to another in the network	N/A	21
Density	The proportion of all possible dyadic connections that are presented in the network	0-1	0.000002
Reciprocity	The proportion of all pairs in the network that have a reciprocated tie between them	0-1	0.0016
Clustering coefficient	The degree to which nodes in the network tend to cluster together	0-1	0.000003
Indegree centralization	The extent to which the distribution of indegree centrality in the network deviates from a perfectly equal distribution	0-1	0.1169
Outdegree centralization	The extent to what the distribution of outdegree centrality in the network deviates from a perfectly equal distribution	0-1	0.00017
