Social Networks Theory is a concept that studies the relationships between individuals or groups, and how these relationships affect their behavior and actions. It aims to understand the dynamics of social structures and how information, resources, and influence flow through them.

History of Social Networks Theory

Social Networks Theory emerged in the 1930s when researchers started studying social structures and their implications on society. However, it was not until the 1970s that the concept gained popularity among sociologists, anthropologists, and psychologists. Since then, several scholars have contributed to its development.

Key Concepts of Social Networks Theory

The key concepts of Social Networks Theory include nodes, ties, centrality, and homophily.

Nodes

Nodes refer to individuals or groups that are part of a social structure. They can be people, organizations, communities or any other social entity.

Ties

Ties refer to the connections between nodes. They can be strong ties such as family or close friends or weak ties such as acquaintances.
