Abstract
The debate on inequality and social divisions in Western cities has been dominated by three positions - the polarization thesis, the 'skills mismatch' thesis and a specific European approach emphasizing the significance of welfare state structures. These three positions are examined with data from Oslo, Norway. It is shown that although income inequality has increased, there is no consistent pattern of social divisions. The evidence provides support both for the polarization and the mismatch thesis, dependent on the unit of analysis and the group in question. It is difficult to spot influences of the welfare state in these data, and it is argued that rising inequality, contrary to service provision, poverty and segregation, approaches a 'closed process'. Increased earnings at the very top, however, may be explained in terms of social networks.
