Large income inequality in Oslo

The income distribution in Oslo is far more unequal than in other parts of Norway. In 2008, the highest income class (the tenth decile) received 25 per cent of all household income after tax in the capital, while the lowest income class (the first decile) received 2.5 per cent of total income.

There are many reasons why Oslo is the place with the largest income differences in Norway. One reason is the high concentration of immigrants in the capital, many of whom have low incomes . The unequal income distribution can also be explained by the peculiar household structure in Oslo, where more than half of the households consist of a single person. This is a much higher proportion than in other large municipalities in Norway. The distribution of income among single person households is generally more unequal compared to other types of households. In Oslo we also find many capital owners that are heavily overrepresented in the very top of the income distribution. In 2008, almost a quarter of all share dividends in Norway were received by share owners situated in Oslo.
