Sociology – at its most broad – is the study of society. Rather than focus on the individual, Sociology’s unit of analysis is the collective, such as the family, the group, the institution, the neighborhood, the city, and the state. Sociology’s chief role in public health is the evaluation of these macro components of society that affect public health at the population level. These evaluations shed light on why inequities in health exist and the mechanisms for long-term change. As the field of public health continues to place increased and vital emphasis on the social determinants of health, sociologists aid by providing long-standing and empirically tested theories on the ways in which race, racism, SES, power, religion, and institutions influence physical and mental health. Sociology’s highly conceptualized approach to interpersonal and intergroup processes are essential for robust public health management.
