Another basic network indicator is density, which essentially reflects how many people in a network are connected (usually directly) to each other. You can imagine that there are a number of possible network configurations based simply on permutations of network size, centrality, and density. For instance, you can have a large or tiny network, be central or peripheral in the network, and have a dense or sprawling network. Each of these structures has implications for how the network might serve its various actors.
