Abstract: Methods and systems for analyzing, improving, and monitoring the co-prosperity of members of a network, an ego network, a subnetwork or affiliated networks, implement the steps of: for each member, profiling the habits of the member and determining a member habit index; profiling the welfare and wellbeing of the member and determining a member success index; determining a co-prosperity index for the member reflecting the member's benefits from and contributions to the network; determining the causal relationships between the member and network relationship habit profiles and the co-prosperity index of the member; developing and delivering a habit improvement program to the member based on the predictive modelling of the impact of changes to the member habit profile and the member welfare and wellbeing outcomes. The method and system may track the effectiveness of the habit improvement program by periodically updating the habit profile of the member and the welfare and wellbeing profile of the member.
