In this article, we attempt the problem of estimation of the population Ratio of mean in mail surveys. This problem is conducted for current occasion in the context of sampling on two occasions when there is Non-response (i) on both occasions, (ii) only on the first occasion and (iii) only on the second occasion. We obtain the loss in precision of all the Estimators with respect to the Estimator of the population Ratio of mean when there is no Non-response. We derive the sample sizes and the
