Abstract: The effect of working status of Bangladeshi women on the decision of age at marriage and fertility in Bangladesh using national representative data from Bangladesh Demographic and Health Survey (BDHS), 2003-2004, allowing for the existence of observed characteristics that affect both age at marriage and fertility. It is well known that working status of women is an important socio-economic variable and that has drawn considerable attention from researchers engaged in the study of fertility differentials and determinants. This study reveals that employed women in such activity contribute in raising age at marriage and thereby affect fertility to reduce. This also, indicated that the singluate mean age at marriage increased about 14 and 23% for male and female, respectively.
