Primary groups are small social units characterized by close, personal relationships. These groups typically include family and close friends, where members interact frequently and share emotional bonds. The connections in primary groups are often deep and enduring, providing support and a sense of belonging. In primary groups, individuals influence each other's behaviors and attitudes significantly. They play a crucial role in socialization, helping members develop their identities and values. Examples of primary groups include nuclear families, peer groups, and close-knit communities, all of which foster strong interpersonal connections and emotional ties.
