An integrated method of analysis and evaluation of factors defining the quality of the urban environment and the level of environmental satisfaction, now being applied in the city of Rome, is described. The impact of various factors on the environmental quality is evaluated with respect to given standards with the help of a series of 'indicators'. These evaluations are compared with those given by a sample of the population on its own residential district in order to verify the relations between the objective aspects of the quality of the urban environment and the way they are perceived at subjective level.
