Abstract
In this paper, we analyzed human network based on information on friendship obtained by interview survey for the elderly in the two community associations located in the Mountanious area. And we also analyzed the relationship between network strength and health indicators. When nodes with high betweenness centrality in the network are omitted, the network became less tight by losing the central person in the network. Focused on relationship between the residential distances and the contact frequency, there is a possibility that the distance between the residential districts is an obstacle to friendship. Focused on relationship between health indicators and in-degree, the score of health indicators tended to increase as the number of in-degree increase, and relationships were found between the strength of the human network and health indicators.
