The interface can frame historical questions more broadly than the loaded evidence. It does not backfill unsupported centuries or carry population-health estimates beyond their source boundary.
| Domain | Observed range | Outside the range |
|---|---|---|
| Organized conflict | 1946-2025 annual; candidate events through July 2026 | No atlas observation before 1946 |
| V-Dem governance | Country-years in the loaded release through its source boundary | No automatic forecast |
| Mortality and total fertility | 1980-2023 | Shown as unavailable, never extrapolated |
| Crude birth rate | 1960-2024 | Shown as unavailable, never extrapolated |
| Total population | 1960-2025 | Shown as unavailable, never extrapolated |
Known interpretive limits
- Absence from a loaded dataset is not evidence that an event did not occur.
- Fatality estimates retain low, best, and high source values where available.
- Country joins can conceal historical boundary changes; source names remain available in raw records.
- Map geometry is reference geometry, not a territorial adjudication.
- Associations among conflict, regime, fertility, and mortality are descriptive until a causal enclosure is specified and supported.
Corrections
Corrections should identify the page, source row or identifier, proposed change, and supporting source. Open an issue in the public repository so the review and resulting change remain inspectable.
