This study was carried out in Jesse kingdom in Ethiope West Local Government Area of Delta
State, Nigeria, to find out the fertility level in the area, its determinants and the implications for the
people of the area. Data used in the study were collected from a representative sample of 1030
women mainly in the age group of 15-19 years. Using the multiple regression, the study examined
the changes in fertility level due to variation in such factors as level of education, types of
occupation, religion/culture and age at first marriage. The findings indicate high fertility levels for
the study area. Early marriage, social values placed on children and child bearing, marriage
pattern, low use of contraception, low level of education and labour force participation, infant and
child mortality as well as political consideration were found to have influenced the fertility behavior
in the study area. The socio-economic implications of high fertility in the study area are discussed.
Also, the strategies for addressing the issue of high fertility in the study area are suggested.
