In various countries we observe governments aiming to produce mixed income
areas to reduce or prevent spatial segregation. This almost always implies
a redifferentiation, or restructuring of the housing stock of low-income ar
eas. This strategy has its advantages and disadvantages. Redifferentiation
and restructuring are based on the idea that solutions to the problems of s
patial segregation and concentration can be found in the housing stock. Thi
s is also the case in the Netherlands. Since 1997, the Dutch Government has
advocated a housing policy promoting a restructuring of urban neighbourhoo
ds by building more expensive dwellings in traditionally low-income areas i
n order to influence the income mix in these neighbourhoods, thereby implyi
ng that this is a positive and feasible development. This paper will focus
on the goals of the undivided cities formulated by the Dutch Government and
the arguments concerning the relation between segregation and restructurin
g of the urban housing stock. The paper will also examine the income mix an
d income segregation in Dutch urban areas itself. Is there any reason to ai
m at a larger spatial differentiation of income?
