Central theme of the book is the effect of Migration on demographic aspect. Especially on fertility and mortality, growth pattern, anthropometric variables, and haematology among the Oraons - migrant tea garden labourers of West Bengal and sedente agriculturist of Jharkhand (the then Bihar). Attempts have also been made the effects are due to the factors associated with new habitats, migrant groups, - the Proto Australoid Oraon and Mongoloid Tamang tea labourers. Other Sarameters of comparison like family planning practice, age cohort, length of stay in the new residence and income levels of the two migrant groups have also been considered. This book will be useful for those who are concerned with the tea garden labours and for the post graduate students and researchers of Anthropology, Demography, Sociology, Ecology, Economics and Human Biology including Health Sciences. It will be of great use for the scientists, administrators, pology makers, planners, political and social activists and common publics. The issue of migration has long been a subject of discussion within almost all social and biological sciences.
