The sample is applied on (150) male/female individuals using the Scale of Environmental Convenience as a means for collecting data to be applied on a sample of the poor (Monshaat Naser quarter – Roud El-Farag quarter – Al-Megawreen cemetery). The researcher uses the social survey method for deducing social reality and analyzes the problem ecologically and for giving a conception of quality of life. The researcher uses multiple theories such as (Psychological analysis of Freud – The behavioral school – The human school – the ecological system theory). The research comes to several results which most important are: there are significant statistical differences between the study sample (tomb' residents/slum quarter) on Scale of Environmental Convenience.
