Income differentials decreased slightly in 2020
Statistics Finland's income distribution statistics show that income differentials decreased slightly in 2020 compared with the previous year. Real income increased by 1.5 per cent in two lowestincome deciles from 2019 to 2020. The income level of the population's highestincome decile increased by 0.3 per cent. The income of medium income earners (income deciles V to IX) remained at the previous year’s level.
Change in average real income (%) by income decile from 2019 to 2020
Income decile: the population is arranged according to income and divided into ten equal parts, each of which has around half a million persons. The first (I) income decile is the lowestincome decile and the tenth (X) is the highestincome decile. Income concept: equivalent disposable monetary income (incl. realised capital gains) of household dwellingunit, average per person. Equivalent income: the householddwelling unit’s income divided by its consumption units (modified OECDscale).
In 2020, the Gini coefficient describing relative income differentials received the value 27.7, which was 0.2 percentage points lower than in the previous year and 0.2 percentage lower than in 2010. Compared with 1995, the Gini coefficient has grown by around 5.5 percentage points. Most of this is caused by the fast growth of income differentials at the end of the 1990s. The income differentials have been at their lowest in the mid1980s. The Gini coefficient gets the value 0 if everyone receives the same amount of income and 100 if one income earner receives all the income. The higher the Gini coefficient, the bigger the relative income differentials are.
