State-led new-build gentrification in metropolitan Oslo

A significant body of literature has demonstrated how urban revitalisation policies and market-oriented housing policies facilitate new-build gentrification in large-scale redevelopment projects. This study takes sustainable urban development as the point of departure and adopts a broader spatial perspective. I investigate how housing construction and densification policies influence ongoing gentrification processes at a metropolitan scale in Oslo, Norway, and I argue that socio-economic changes induced by densification can be characterised as state-led new-build gentrification. The analysis draws on population-wide register data from 2004 to 2022, supplemented by a unique dataset on densification policies. From descriptive statistics, mapping, and fixed-effects regression analysis, my findings reveal three key points: First, market-rate housing construction has a significant gentrifying effect in affordable neighbourhoods, especially in the inner city. Second, policies for urban transformation strengthen the gentrifying effect of new housing and facilitate an outward diffusion of gentrification into inner suburbs. Third, directing market-rate residential developments toward central urban areas reinforces centralisation of affluence and suburbanisation of poverty. The article provides policy-relevant documentation on how compact urban growth policies, combined with neoliberal housing strategies, underpin gentrification in affordable neighbourhoods.
