Communities are types of social systems which are distinguished by the personal or affective nature of the ties that hold their members together. They are groups of people who sense a common identity and bond with one another and who are attached to one another through regular interaction. Well, it is also an identificational community because the community members have a lot in common, most importantly, low social class and race. A case of the haves versus the have nots.
