This paper investigates the relationships between migration and the determinants of contraceptive use in Kenya based on the 1988/1989 Kenya Demographic and Health Survey (KDHS). The KDHS collected detailed information on pregnancies, contraceptive use, marriage, employment, places of residences and how long one has lived in these places of residences. The paper examines whether the contraceptive use dynamics of women who migrate characteristically differ from that of non-migrants in Kenya. The principal hypothesis of the paper is that women who migrate comprise a group who acts rationally to maximise their other lifetime aspirations at the expense of their reproductive roles. The study further assumes that through the influence of fertility process by migration characteristics, contraceptive use is also influenced. The association between the process of migration and contraceptive use dynamics is analysed using cross-tabulation with percentages and logistic regression analysis. The findings show that, in Kenya, migration influences contraceptive use among migrant women. That is, the probability of using contraception is higher among the migrant women than the non-migrants. The issue is important to researchers and policymakers. Because fertility behaviour is influenced by change and characteristics of place of origin and destination, public policy interventions is necessary in order to account for the residential experience of women served by family planning and maternal child health programmes in different places
