Data revision policy - Eurostat
Data revision is a fundamental component of producing high-quality statistics, ensuring that published figures accurately reflect reality as new and improved information becomes available. Eurostat has established a comprehensive revision policy grounded in the European Statistics Code of Practice, which mandates that revisions follow standard, transparent, and well-established procedures. This framework aims to harmonize revision practices across all statistical domains, providing clear documentation and transparent explanations for users regarding the reasons and scheduling of data updates. The policy categorizes revisions into routine, major, and unscheduled types, each serving distinct purposes in maintaining data integrity. Routine revisions occur regularly as updated source data is received or seasonal adjustments are applied. Major revisions are pre-announced and triggered by significant methodological changes, new classification standards, or the introduction of infrequent data sources like censuses. In contrast, unscheduled revisions address errors detected by national statistical offices or Eurostat, ensuring that mistakes are corrected promptly to maintain trust in the statistical output. This article is highly relevant to open data because it underscores the necessity of transparency and metadata in digital information ecosystems. By explicitly publishing revision policies and practices within metadata files, Eurostat enables users to understand the lifecycle and reliability of datasets. For open data initiatives, this approach highlights that data is not static; robust access to revision history and methodological context is essential for users to interpret, analyze, and trust the information they utilize.
