Sex-Composition Of Children And Fertility Desire In Vietnam, Hai Yen Thi Nguyen
Sex-Composition Of Children And Fertility Desire In Vietnam, Hai Yen Thi Nguyen
Chulalongkorn University Theses and Dissertations (Chula ETD)
This thesis aims to investigate whether the variation in sex composition of children can explain the variation of Vietnamese women's fertility desire. Vietnam has experienced rapid fertility decline since the middle of the 20th century but within a broader context of strong cultural norms regarding son preference. Thus, the sex composition of children is one of the key determinants of reproductive behavior within Vietnam. To my knowledge, no previous study has examined the relationship between sex composition of children and women's fertility desires in Vietnam. Using data from the 2014 Vietnam Multiple Indicator Cluster Survey (MICS) I investigate the association …
