This study compares the performance of various calibration ratio estimators in estimating the mean weight of newborn babies at the maternity ward of Federal Medical Centre (FMC), Umuahia, Abia State Nigeria, under stratified random sampling. Data were collected on maternal age, height, weight, and baby-related variables such as weight, gestational age and height. The maternal body mass index (BMI) was utilized as the stratification variable. The aim is to improve the accuracy of estimating mean weight of babies by incorporating gestational age as an auxiliary variable. An empirical study was carried out through population data sets obtained as to ascertain the efficiency and performance of various calibration ratio estimators considered in the study, and the results revealed that the estimator of Audu et al(2020) outperformed the other estimators, and has proven to be consistent in all cases of sample size selection and the tuning parameter.
