How this figure is calculated
Population in urban agglomerations of more than 1 million divided by Population, total, matched on country and year. Neither publisher issues this ratio as a series; it is computed here from both.
Population in urban agglomerations of more than 1 million ÷ Population, total
Computed from
- Population in urban agglomerations of more than 1 million World Urbanization Prospects 2018, United Nations (UN)
- 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.
