Both migrant groups were tea garden laborers working in the Birpara, Lankapara, and Tulsipara tea gardens in the Jalpaiguri district, West Bengal, India. The present study reveals that the migrant Oraon possess significantly higher fertility and (infant) mortality than the sedentary Oraons even though they are a genetically similar group.
