Urban sociology is the sociological study of cities and urban life. One of the field’s oldest sub-disciplines, urban sociology studies and examines the social, historical, political, cultural, economic, and environmental forces that have shaped urban environments. Like most areas of sociology, urban sociologists use statistical analysis, observation, archival research, census data, social theory, interviews, and other methods to study a range of topics, including poverty, racial residential segregation, economic development, migration and demographic trends, gentrification, homelessness, blight and crime, urban decline, and neighborhood changes and revitalization. Urban sociological analysis provides critical insights that shape and guide urban planning and policy-making.

Georg Simmel was a German sociologist, philosopher, and critic.
