  "de": "Italien laesst sich aus den oeffentlichen OECD-Mikrodaten nur fuer 2015 regional auswerten, und dort nur fuer die vier adjudizierten Gebiete Bozen, Trient, Lombardei und Kampanien; alles uebrige faellt in eine Sammelkategorie. In den Files 2018 und 2022 ist die Ziehungsschicht komplett maskiert („Undisclosed STRATUM“) und eine Regionsvariable fehlt — regionale Auswertungen sind daraus nicht moeglich. Fuer Regionalwerte ist INVALSI die geeignete Quelle.",
  "en": "Italy can only be broken down regionally for 2015 in the public OECD microdata, and then only for the four adjudicated areas Bolzano, Trento, Lombardy and Campania; everything else is pooled. In the 2018 and 2022 files the sampling stratum is fully masked (“Undisclosed STRATUM”) and no region variable exists, so regional analysis is impossible. For region-level figures INVALSI is the appropriate source."
