Fertility Behavior in the Context of Polygyny in Pakistan With the Moderating Effect of Household Wealth Status Evidences From Demographic and Health Survey 2017–18

This interaction between wealth and polygyny highlights a complex dynamic, suggesting that wealth amplifies fertility within polygynous unions, diverging from the general trend of declining fertility with increasing wealth.
