The book focuses on understanding the dynamics of current internal migration in Nigeria and implication for changing reproductive behaviour and family planning adoption. Migrants and non-migrants differ in terms of cultural affiliations and socio-demographic characteristics which may have implication for changing fertility behaviour and family planning. The study relies on data from the 2008 Nigeria Demographic and Health Survey (NDHS) to provide empirical evidence on the interrelationships between migration, fertility and family planning with a profound focus on Nigeria. Findings of the study will provide a framework and guidelines for effective and coordinated programmes for addressing issues of high fertility and low contraception in Nigeria, even as the country moves towards achieving the Millennium Development Goals (MDGs) 1, 4 and 5. The author, Mr. Omoyeni Sunday, is a scholar with a considerable experience in data analysis and research with a profound focus on fertility and reproductive health. He is currently working as a Programme Assistant with the International Organization for Migration (IOM), Abuja, Nigeria.
