World Cohort Share Calculator
What share of a global cohort any national cohort represents, and how that changes as the world grows.
A 95 million national cohort inside a 2.01 billion global cohort is 4.7% of it — about one child in every 21 — and that share rises to 5.9% over fifteen years at 1.5% growth.
