How this figure is calculated
Number of one-year-olds who are not vaccinated against diphtheria, pertussis and tetanus divided by Population, total, 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 ÷ Population, total
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
- 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.
