Maybe this is actually referring to Unity Day when the Ark came together. Perhaps it really means that ~60 years ago (3 generations) is when the Stations formed the Ark. Prior to that, the previous generations were isolated on their own Stations, leading to separate population equations for each Station. Like, maybe individually, some of the stations were able to support more people but once they joined the Ark and combined with the other populations (that might have been dying off without the additional stations), it caused the population overload causing the necessary one-chiild law.

It might also explain why American English is prevalent if the US Station had the most people when they joined with the other Stations (and interbreeding caused most all families to get stuck with at least one native English speaking parent).
