How this figure is calculated
Number of one-year-olds who are not vaccinated against diphtheria, pertussis and 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 one-year-olds who are not vaccinated against diphtheria, pertussis and tetanus ÷ Land area (sq. km)
Computed from
- Number of one-year-olds who are not vaccinated against diphtheria, pertussis and tetanus WHO & UNICEF (2025); UN, World Population Prospects (2024) – processed 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.
