Does birth month affect a child's chances of turning pro? In Japan, where the school year starts in April, 33.1% of J.League players in 2018 were born in April-June and only 16.1% in January-March. Europe's top leagues show the same pattern. In BC, age groups use a January 1 cut-off, so the youngest players are born in October-December. A slow start can simply be age, not ability. ⚠️ Data note: these are population patterns from published studies, not a prediction for any one child.
