Humes are the most common race in Ivalice, making up about 40% of the population. They have no special abilities, and have the second shortest life span of any race in Ivalice (roughly 60 years), next to the aegyl. Despite this, they have managed to set up large empires and kingdoms all over the continent and effectively achieved global dominance due to their industrious nature. Humes can be compared with moogles in this regard, and probably have the closest relationship with the moogle than any other race, as seen in many instances when moogles are employed by humes. However, races of all kinds inhabit hume settlements.

Hume characteristics in Ivalice vary, but there are visible patterns based on location. For example, Dalmascans generally have darker skin and light hair, whilst Archadians are paler with darker hair.
