Our society is an urban society. As a nation, we have made the transition from rural to urban in less than fifty years. Perhaps no other trend has had such a profound effect on our way of life as the trend toward increasing urbanization. The modern city is a product of a complexity of geographic, economic, cultural, and social factors. A superficial look at the city reveals only a structure of streets, blocks, business places, and residential buildings. The individual seems lost in the maze. But upon closer observation the city is found to exhibit definite patterns. It is toward a better understanding of one of these, the patterns of intra-city population mobility, that this study of Wichita, Kansas is directed.
