Among these approaches, the "social mix policy" which is effective in many European and US cities has an important place. According to this approach; poverty is concentrated in low-income housing areas associated with low-income, unemployment and crime, thereby the socio-spatial segregations are deepening. Therefore, it was aimed to prevent these problems by restructuring and reconstructing the social housing which is the habitat of the low-incomes, arranging these areas to live together with the low and middle-income people. In Turkey, this perspective of urban transformation approach and rhetoric became prominent in the 2000s.
