Glossary:Income quintile share ratio
From Statistics Explained
The income quintile share ratio or the S80/S20 ratio is a measure of the inequality of income distribution. It is calculated as the ratio of total income received by the 20 % of the population with the highest income (the top quintile) to that received by the 20 % of the population with the lowest income (the bottom quintile).
All incomes are compiled as equivalised disposable incomes.
