The Burgess Concentric Model is a theoretical framework that explains urban land use and the social structure of cities, developed by sociologist Ernest W. Burgess in 1925. It illustrates how a city grows outward in a series of concentric rings from the center, with each ring representing different socio-economic groups and land uses. This model highlights the relationship between urban growth, social stratification, and the distribution of different residential areas, providing insight into the internal structure of cities.
