Number of one-year-olds who are not vaccinated against diphtheria, pertussis and tetanus ÷ GDP (current US$)
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
- GDP Country official statistics, National Statistical Organizations and/or Central Banks
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.
