"Under certain simplifying assumptions, an inflated generalized Poisson distribution has been proposed to study the trends for out-migration. This distribution has been fitted to data estimating the parameters by (i) method of moments and (ii) maximum likelihood method....Asymptotic expressions for variance and covariance of the maximum likelihood estimates are obtained." The method is tested using data from the Rural Development and Population Growth survey undertaken in Varanasi, India, in 1978.
