This study explores the course and age-parity structure of fertility decline in Kenya. The study utilizes pooled data from the 1988 and 1993 Kenya Demographic and Health Surveys. By using parity progression ratios and conditional age-parity specific birth probabilities, it provides a clear picture of the dynamics of the fertility decline that is under way in Kenya. It can be argued that the observed fertility decline is not only a timing effect but is also due to a true decline in the number of children various age cohorts of Kenyan women have been having. In the early and middle ages of reproduction, we see important tendencies toward the delay of the first birth and the lowering of middle and higher order births. Together, these changes are producing dramatic declines in period fertility
