How this figure is calculated
Coal production divided by Land area (sq. km), matched on country and year. Neither publisher issues this ratio as a series; it is computed here from both.
Coal production ÷ Land area (sq. km)
Computed from
- Coal production Energy Institute - Statistical Review of World Energy (2026) and other sources – with major processing by Our World in Data
- Land area FAOSTAT, Food and Agriculture Organization of the United Nations (FAO)
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.
