Data sources
Atlas uses Eurostat datasets with their original units and provenance.
Geographic scope
Country comparisons use the 27 EU member states when the dataset supports them.
Story discovery
Python calculates rankings, changes, long-term movement, distribution gaps, outliers and records.
Interestingness and size bias
Interestingness combines magnitude, rarity, recency and data quality. Absolute metrics receive a size-bias penalty when a result only reflects country scale.
Fact checking
Important values, units, rankings and changes are reproduced from processed data before publication.
Opportunity Engine
Current-spike signals from Google Trends are separate demand signals, never statistical facts. No current spike does not mean no demand.
Publication Gate
Pages need sufficient facts, comparisons, provenance, chart support, confidence and original value. New publication is limited to three per run.
