Previous research: The underlying causes of neighborhood racial change

  • David P. Varady


Beginning in the 1920’s human ecologists utilized the concepts of invasion and succession borrowed from plant and animal ecology to explain changes in the ethnic composition of urban neighborhoods (Park, 1936a; 1936b; Hawley, 1950). These changes were assumed to follow basically the same laws whereby one plant or animal species replaces another in a given territory. According to the succession model, change results from the ‘push’ of increasing numbers of a new ethnic group which leads members of the more established group to move to a newer area closer to the periphery of the city (Burgess, 1928:112). Competition between the new and established group over land use is assumed to be an inherent aspect of the succession process — with competition often assuming the form of conflict (Park, 1936a).
