Groups are a basic part of society and social life, and of particular interest to sociological study.
People belong to many social groups of all different levels at the same time. A social group is simply a collection of two or more people who regularly interact with each other for some purpose.
EXAMPLE
Couples, family, friends, business associates, coworkers, or lifestyle groups like activist groups, environmental groups, or even your neighborhood church, are all social groups that are part of an individual’s regular interactions.There are two kinds of social groups:
You're bound together by loyalty and emotional connection--you can't go out and replace your brother in the same way that you can replace a coworker. Primary groups are the very first form of human group contact and interaction, which is why they are called primary. You first experience the family, and then the friends.
Primary groups provide your ideas of right or wrong, your attitudes and behaviors, your worldview and outlook.
EXAMPLE
Whether a person is religious or not, or conservative versus liberal, is often shaped in his or her very first primary group contact.The following represent secondary groups--people you see occasionally, whose faces are familiar to you, but you don’t really know that much about them.
You’re still united in a way, because you share a group affinity, but in the event that the unifying circumstance is dissolved--soccer league or class ends, change of job, etc.--that secondary group also dissolves.
