A class of almost unbiased ratio estimators for population mean hivin Y is derived by weighting sample hivin y=(1/n) SIGMA y-i, ratio estimators ( hivin y hivin x) ovrhdot X and an estimator, ( hivin x/n) SIGMA (y-i/x-i). It is shown that Nieto de Pascual (1961) estimator is a particular member of the class and an optimum estimator in the class (in the minimum variance sense) is identified. The results are illustrated through two numerical examples.
