Cohort Crossover Finder
The year one cohort overtakes another in a country — or why it never does.
Nigeria's Generation Beta cohort, adding roughly 8.7 million a year against 95 million Alphas, overtakes the older cohort in about nine years — set the annual addition low enough and the crossover never happens at all.
