The Dutch social rental sector often serves as an example for other countries as a result of its large share and good quality housing. However, many things have changed in the sector in recent years. After 2011, the central government has regained its control over the housing associations. This was needed after the unacceptable amount of scandals that characterized Dutch social housing after 2000. Unfortunately, some of the new housing policies direct the sector into the direction of a residualization (the sector becomes smaller and there is a larger concentration of lower income groups). This is undesirable because the challenges that housing associations have to face are bigger than ever. Housing shortages are increasing, housing affordability is under pressure and spatial segregation is growing.
