Abstract Following SEN & GERIG (1975) an estimator for the population mean on the current occasion is proposed. It has been shown that the estimator is more efficient than ‘mean per unit estimate’ for all kind of populations. The eetimatiors suggeated by SEN & GERIG (1976) and SEABM (1964) are also found to be relatively less efficient than the proposed estimator.
