Political sociology is a field of research concerned with studying how oppression and power play in modern society at both micro and macro levels. The field has a focus on the study of politics, institutions, organizations, communities, and nations as well as their interactions. It is also interested in the study of popular societal factors that affect change through periods of history. As political science, political sociology uses many of the same methods of social science research as applied in other types of social sciences. The major areas of focus in political sociology include socio-cultural organization, political leadership and power, gender issues, economic policies and institutions, marketing, and politics.
