Compare scenarios without losing provenance
The instrument travels through shared observed history and into named official or StrategicBase futures. Scenario controls never rewrite observations or silently interpolate an unavailable year.
Waiting for the released model bundle.
Model fidelity
The StrategicBase cohort engine is compared with direct Eurostat baseline states and flows. Errors are diagnostic, not uncertainty intervals.

Population pyramid
Source-recorded male and female population by single year of age; the terminal age may be open-ended.
Population trajectory
Observed history is solid; official and StrategicBase futures are dashed beyond the 2025/26 boundary.

Interpretation boundaryOfficial projections are conditional source scenarios, not observed future populations. StrategicBase scenarios, when present, remain separate named runs. A transport or bundle failure is not factual absence.
