This article examined the determinants of child mortality namely; cultural, economic, demographic, community health and nutrition in a multiethnic village of West Bengal. The findings reveal highest level of child mortality among the scheduled tribes (ST) and lowest among the general castes (GC), while other backward castes (OBC) and scheduled castes (SC) show an intermediate position. Large differentials were found in child nutrition. While, 52.94 percent of the GC children fall in the category of normal status of nutrition, only 25.64 percent of the SC children fall in this category. Among the OBC and ST children this frequency is 44.44 and 31.58 respectively. In addition, it is found that more than 28 percent of the GC and OBC mothers fall in the category of underweight, whereas, 35 percent of the SC and ST mothers were underweight. The study inferred, general castes enjoy better nutrition and health care facilities, who are more health conscious than other backward castes, scheduled castes and scheduled tribes. Other backward castes show a similarity with the general castes in this respect. On the other hand among the scheduled castes a reverse trend is perceptible. They show a similar trend with the scheduled tribes in respect of health and nutrition. It is to be mentioned that both the scheduled castes and scheduled tribes occupy the lower segment in society in Sahajapur village.
