Abstract

Consider several disjoint social networks. What is the minimum number of bridges (i.e. edges between nodes belonging to different social networks) or central nodes (those who are endpoints to a bridge) required so that every two nodes are connected by a path of length at most $k$? The answer depends only linearly on the size of the social networks for $k=2$, and does not depend on the size of each social network for $k \geq 3$. Our findings provide an equality of opportunity measure for social networks which is easy to compute and verify, and which can be used to compare the degree of integration of a variety of real-life social networks.

Keywords: social integration, social networks, small world, equality of opportunity
