Miqo‘te in general are the less seen race in lore - but just making a visit in limsa shows us there are tons and tons of adventurers, which again is kind of lore breaking.
„Comparatively few in number, Miqo'te maintain an insular mentality within their clans, tending to avoid contact with the other races. Many lead isolated lifestyles, even when living in the more populous cities.“

The Males are even scarcer, this is from a dev post on the official forums:
Though there are ten suffixes listed above, rarely do even the largest Keeper of the Moon families have more than two or three sons. This is not by choice. Nature merely sees to it that more females are born to this race.

I‘ll update the info, but think i‘ve read somewhere that in 8 females, 1 male is born? but i‘ll update the post as soon as im home and have time to do the research.
