Odd that the youngest bracket (14–19) is bounded with a minimum age of 14. There have been a handful of births from younger mothers in the past 30 years (a 10 year old girl in 2006 in the US). Insignificant in the total graph, but weird to exclude given that the oldest bracket is open-ended (>50). Just renaming the bracket to ≤19 would suffice.
The youngest documented mother ever was 5 years and 7 months (Peru, 1939).
