Cohort Comparison Calculator
Compare any two birth cohorts on size, age and share of the world, including the years between their midpoints.
Generation Alpha and Generation Beta are both exactly 15 years long with midpoints 15 years apart, which makes them the first two cohorts in the naming sequence to be defined identically.
