In India, due to the lack of age-specific death and birth data, direct calculation of Net Reproduction Rate is not possible, particularly at the district level. Also, conventional Net Reproduction Rate and intrinsic growth rate measures are not suitable for populations affected by migration. The present study attempts to recapture the scenario of migration in the districts of two diverged states of India—Kerala and Assam—by estimating the Net Reproduction Rates before and after allowance for migration. The study also attempts to assess the speed of population growth of these districts from the intrinsic growth rates in the presence of migration.
