This paper analyzes the socioeconomic determinants of fertility in Zambia. The Poisson regression model is used. The dependent variable is a count variable denoting the number of Children Ever Born (CEB) to a spouse which takes on non-negative integer values. Analysis of this study is based on the 2014 cross sectional data from the Zambian Demographic and Health Survey collected by the Central Statistical Office (Zambia) and Macro International Inc. The results indicate that the woman’s wealth/income, education, female autonomy, use of contraceptives place of residence, region, labour force participation and access to media affect fertility in Zambia.
