How this figure is calculated
Number of confirmed cases of tetanus 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.
Number of confirmed cases of tetanus ÷ Land area (sq. km)
Computed from
- Number of confirmed cases of tetanus World Health Organization – Global Health Observatory (2026) – with minor 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.
