Well the answer given at the lore panel was essentially "they all live to be about the same age but Elezen live a little longer because their childhood is a little longer."
There was no specification.
Age scales? How long do they live?
-five races biologically live similar life spans as real world. 100-120 possible. But because Eorzea is so harsh, it’s much less likely for someone to live out their full life expectancy. BLM lalafell IS an exception to the rule. Elezen have slightly extended lifespan from other FOUR races. Childhood for elezen lasts longer than others.
