How this figure is calculated
Pertussis - number of reported cases divided by Population, total, matched on country and year. Neither publisher issues this ratio as a series; it is computed here from both.
Pertussis - number of reported cases ÷ Population, total
Computed from
- Pertussis - number of reported cases World Health Organization, Global Health Observatory
- 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.
