And this means that population in a city is distributed predominantly according to the income, which results in fragmented city: “social division in the post-industrial city suggests that it can be carved into distinctive quarters: (a) the luxury city, segregated in enclaves of specific, isolated buildings in the city occupied by the economic, social and political elite; (b) the gentrified city, occupied by the professional, managerial and technical social groups; (c) the suburban city, apartments near the city centre or outer city housing, occupied by “mid-range” professionals and civil servants; (d) the tenement city, often occupied by “blue and white collar” workers in the rented sector, which includes social (public) housing; (e) the abandoned city, “the end result of trickle down, left for the poor, the unemployed, the excluded.” [11].
