How this figure is calculated
The year-on-year percentage change in Theoretical duration of lower secondary education (years). Computed from consecutive annual observations; years either side of a gap are skipped rather than bridged.
Computed from
- Theoretical duration of lower secondary education UNESCO Institute for Statistics
Statizoid computes this series; the underlying measurements belong to the publishers named above. The arithmetic is applied to every country and year where both inputs report, and nothing is estimated unless the page says so.
