The indicator is part of the EU Sustainable Development Goals (SDG) indicator set. It is used to monitor progress towards SDG 10 on reducing inequality within and among countries; which is embedded in the European Commission’s Priorities under 'Supporting people, strenghtening our societes and our social model'. SDG 10 among other things, calls for nations to adapt polices and legislation to increase the income of the bottom 40 % of the population and to reduce inequalities based on income, sex, age, disability, race, class, ethnicity, religion and opportunity.
Furthermore, the indicator is included as a key indicator in the Social Scoreboard for the European Pillar of Social Rights.
One of the objectives of the social policies in the EU is to reduce inequality by providing equal opportunities for all. Analysing the inequality of income distribution is one of the ways to measure inequality within EU countries. As a measure of the inequlity of income distribution within a country, the indicator complements the indicators on the income share of the bottom 40 % and on the at risk of poverty gap.
4.1. Data description
The indicator 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.

4.4. Accuracy - overall
From 2021 Regulation (EU) 2019/1700 foresees the requirements relating to geographical coverage, detailed sample characteristics, including subsampling, in accordance with Annex III, common data gathering periods, common standards for editing and imputation, weighting, estimation and variance estimation.
Before 2021 onwards EU-SILC is based on a common framework defined by harmonised lists of primary and secondary variables, common concepts, a recommended design, common requirements (such as imputation procedures, weighting, sampling errors calculation) and classifications aiming at maximising comparability of the information produced. Details can be found in the metadata of the source datasets.
