How this figure is calculated
Total tetanus - number of reported cases 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.
Total tetanus - number of reported cases ÷ Land area (sq. km)
Computed from
- Total tetanus - number of reported cases World Health Organization, Global Health Observatory
- 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.
