Well, I would estimate the number of independent western women living overseas (without the inevitable husband in tow) at less than 1% ( if that) of western expats. I’ve never come across one in fact. Most younger women would always return home to further career, marry & start families. A quite separate way smaller demographic with undoubtedly their own contact networks.
Women by evolutionary design are not “wanderers” ; they ultimately stay close to original home & family rather than seek new ones like many men obviously do here.
