Income (or wealth) inequality is measured using the normalised Gini coefficient. The normalised Gini coefficient (unlike the traditional Gini coefficient) takes into account negative values in a distribution. The Gini coefficient is a value between between 0 and 1. A value of 0 means that every household has exactly the same income (or wealth). A value of 1 indicates maximum inequality: one household has all the income (or wealth). Since 2011, the margin of error of the Gini coefficient has been small due to integral observation. At the national level, the margin of error is 0.002.
No Gini coefficients are presented for municipalities with fewer than 2,500 households. The coefficients for municipalities are shown to two decimal places. Back to article
