How this figure is calculated
Surface area (sq. km) divided by Population, total, matched on country and year. Neither publisher issues this ratio as a series; it is computed here from both.
Surface area (sq. km) ÷ Population, total
Computed from
- Surface area FAO electronic files and web site, Food and Agriculture Organization of the United Nations (FAO), publisher: Food and Agriculture Organization of the United Nations (FAO)
- Population, total World Population Prospects, United Nations (UN)
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.
