summary In this paper strategies based on a two‐stage successive sampling scheme are proposed for estimating the ratio of the population totals of two characters on the most recent occasion. It is found that the proposed strategies perform better than the standard ratio when used in estimating the ratio of farmers' income to non‐farmers' income. But when applied to the estimation of ratio of girth to height of teak trees, a loss in efficiency is observed.
