Development Pathways of Large Housing Estates in Post-socialist Cities: An International Comparison

Large housing estates in former state-socialist countries had been hardly affected by social erosion before the political changes. However, the emergence of new, capitalist forms of housing after 1990 started to endanger the position of large housing estates on the local housing market. The question was repeatedly raised in the literature about whether large housing estates of post-socialist cities would experience physical decay and social downgrading similar to the West. This paper investigates the socio-economic differentiation of large housing estates in the former state-socialist countries using a case study approach. Housing satisfaction and mobility of residents in four post-socialist housing estates were analysed through a standardised household survey. Empirical data confirm that despite their similar physical appearance, the attitude of people towards large housing estates and their position on the local housing market vary significantly. The authors conclude that even though socialist large housing estates are affected by social downgrading, nevertheless they represent relative social stability and can offer affordable housing to people who are at the start of their housing career.

Post-war large housing estates in Norway – Well-kept residential areas still stigmatised?

The large post-war housing estates constitute an important part of the housing resources in the large Norwegian cities, and the estates seem to present fairly satisfactory conditions physically and socially, compared to similar areas in other countries. Even so, Norwegian large housing estates are held in low esteem. Many of them are stigmatised, and there are some examples of areas facing grave problems. There are several reasons why large housing estates are held in low esteem and have a rather low score on socio-economic and social indicators. Low attraction, low preference for high-rise living, a deregulated housing market, the labelling process, spatial inequality and increasing socio-economic inequality have an impact on segregation and deprivation. We identify some additional factors to explain why large housing estates in Norway still seem to offer fairly satisfactory conditions: a mixed housing stock, the small size of Norwegian cities and estates, a growing local housing market, tenure (low proportion of rented dwellings and public housing), the composition of the occupants, low unemployment rate and a highly redistributing welfare system. Still, many estates are stigmatised and to a certain degree deprived. In these areas we see a need for initiatives to improve the situation. The results of most area-based initiatives in Norway have been positive, but it requires a long-term engagement, a broad perspective and variety of actions, close cooperation with the residents and sufficient resources. The housing co-operatives (co-ops) can create a good starting point for such processes of change when most of the population are already organised through co-ops.     

Trends of out-mobility from large housing estates in Stockholm: influences of the housing policy and neighbourhood context

Since 1990s Stockholm housing market has seen deregulations in accordance with liberalization trends in other European welfare states. The new governance principles together with increasing immigration and public rental housing conversions into cooperative housing in attractive inner city areas have put pressure on still rental-dominated estates because fewer rental dwellings must now cater to expanding numbers of people who have little choice on the housing market. In recent decades, many estates have displayed increasing signs of stigmatization, social exclusion, and outflow of relatively affluent people. This paper improves our knowledge of how the housing policy and economic changes have affected out-mobility from the housing estates in case of three cohorts of young people and how the childhood neighbourhood conditions affect this. Individual annual Swedish registry data (1990–2014) are employed to longitudinally study the out-mobility patterns of three cohorts that grew up in the estates against the backdrop of marketization, growing inequality and deteriorating conditions. This study supplements the existing literature on housing estates by clarifying how income has become more and ethnicity less important over time in explaining sorting patterns from these estates. However, the combination of the two has determined sorting throughout the study period. Growing up in a higher socioeconomic status neighbourhood had modest impact on reducing socioeconomic differences in out-mobility from the estates, while leading to more sorting based on ethnic background.
