Population aged 25-64 by educational attainment level, annual

Annual distribution of the population aged 25-64 in private households across three educational attainment levels, for EU member states, EFTA countries, EU candidate countries and EU/euro-area aggregates. Eurostat dataset edat_lfs_9912 ('Population in private households by educational attainment level and country of birth'), filtered to freq=A, age=Y25-64 ('From 25 to 64 years'), sex=T ('Total'), unit=PC ('Percentage'), c_birth=TOTAL (all countries of birth), and the three headline ISCED 2011 groups: ED0-2 ('Less than primary, primary and lower secondary education', levels 0-2), ED3_4 ('Upper secondary and post-secondary non-tertiary education', levels 3 and 4) and ED5-8 ('Tertiary education', levels 5-8). Each row is one (year, country, attainment level): the share of the 25-64 population whose highest completed education falls in that level. Method: Eurostat compiles the Labour Force Survey microdata transmitted by the member states; private-household population only. Units: percent of the 25-64 population. Caveats: the three shares sum to 100 within each (country, year) up to one-decimal rounding - they are a composition, not independent rates; educational attainment is self-reported in the LFS and national classifications follow ISCED 2011 mapping; the UK, Kosovo, Russia and Belarus are dropped (same licensing rule as the other Eurostat datasets). Coverage: ~37 geographic units after the geo rule, 2004 to the present. Provenance: Eurostat keyless JSON-stat API, free reuse with attribution (Commission Decision 2011/833/EU) - please cite Eurostat. Primary key: (year, country_code, education_level). Join keys: country_code (ISO 3166-1 alpha-3), year. Cadence: refreshed yearly; Eurostat updates the LFS education indicators in autumn (2026-09-10 vintage). Sample use: filter education_level='ED5-8' to track tertiary attainment of the working-age population, or compare ED0-2 shares as a proxy for low-skill labour supply.
