Statistics Poland — Local Data Bank (BDL)

Statistics Poland (Główny Urząd Statystyczny, GUS) · Per-subject and irregular: BDL updates each subject on its own schedule and publishes a lastUpdate timestamp for every one (2026-02-05 for registered unemployment, 2026-04-01 for the regional national accounts, 2026-05-06 for the population balance, 2026-06-15 for regional wages, all observed 2026-08-06). Regional national accounts arrive with a long lag — the most recent year is flagged as a preliminary estimate (attrId 9) and is later revised — and the 2021 census rebased the whole population series.
