Social network structure describes the makeup of the overall social network. There are a number of major factors shaping the overall make-up to a social network including the density of connections being a primary factor as it tells us how connected an agent is on average; the average path length is a second key overall metric as it tells us how close together any two agents are on average.
Social network analysis is the application of network theory to the modeling and analysis of social systems. It combines both tools for analyzing social relations and theory for explaining the structures that emerge from distributed social interactions.
Social resilience refers to the adaptive capacity, of a social system of any kind - from whole societies to individuals - to deal with change within their environment while maintaining and preserving critical structure and functionality.
