Sociology is about social life in a wide sense. Sociologists study relations between humans in small and large social communities, between individuals, groups and organisations at the local, national and global level. Sociologists are concerned with human activities and actions tending to have a pattern or a structure that is relatively independent from single individuals. Sociologists work to explain and interpret how people are shaped by societal conditions and simultaneously are able to change these conditions through their actions and reactions. The study of sociology can focus on everything from analyses of meetings between individuals to in-depth investigations of global processes.
