How this figure is calculated
Population ages 0-14, female 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.
Population ages 0-14, female ÷ Land area (sq. km)
Computed from
- Population ages 0-14, female World Population Prospects, United Nations (UN), publisher: UN Population Division
- 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.
