Hello99:
Regarding the Moslem communities:
In a Atlas published the the 1990’s about muslim society (that covered all kinds of social and economic issues) they devoted two pages to the “shiddcuh crisis” and how age gap is creating it. They make the point that the muslim countries/societies/communities where the age gap is most prevalent (birth rate growth x differential in standard age at time of marriage) they have two other prevalent phenomena regarding their single women
1. Polygamy (women marrying men who are already married)
2. repudiation (women marrying men who have been divorced or widowed.
They explain it simply that since the single women can’t find single men to marry- they instead marry men who are married or who have been married already.
sound familiar…
