Income quintile share ratio S80/S20 (annual, Europe)

Annual income quintile share ratio S80/S20 - the total income received by the 20% of the population with the highest equivalised disposable income divided by the total income received by the 20% with the lowest equivalised disposable income - for EU member states, EFTA countries, EU candidate countries and EU/euro-area aggregates. Eurostat dataset ilc_di11 ('Income quintile share ratio S80/S20 for disposable income by sex and age group'), filtered to age=TOTAL, sex=T, unit=RAT (ratio). Each row is one (year, country). Method: Eurostat compiles EU-SILC microdata transmitted by the member states; income is equivalised disposable income (modified OECD equivalence scale); the ratio is >= 1 by construction - larger values mean more unequal income distributions; non-EU/EFTA/candidate countries are dropped (same licensing rule as the other Eurostat datasets). Units: ratio (dimensionless). Caveats: national EU-SILC redesigns create series breaks for some countries (flagged in Eurostat metadata); the UK is dropped by the connector's commercial-use geo rule; the EU27_2020, EU28 and EA18-EA21 aggregates are included as published. Coverage: ~44 geographic units after the geo rule, 2003 to the present, annual.

Join keys: country_code (ISO 3166-1 alpha-3), year. Cadence: refreshed yearly; Eurostat updates EU-SILC indicators in autumn. Sample use: filter country_code='ROU' to track income inequality in Romania over time.
