The focus of this study is on the types of changes made and the envidenco they proVide showing a process of neighborhood self-definition as implemen ted by residents of a publicly-assisted housing project. Neighborhood self definition is the interactive, resident-initiated process of integrating a social community with a physical one. Definition involves the modifica tion of imagery, function and control of the total environment so that physical and social structures, reinforce and complement one an other. Changes to the physical environment are idioative of this process, based on the assumption that the physical environment is a carrier of social meaning. This meaning is made up of physical association and symbolism as well as interpretation of imagery through the economic, class, normative and associational filters of perception. Active participation in the cre ation of this meaning is a third factor affecting content of the message.
