ABSTRACT

 

Sex ratio at birth has been one of the most studied, yet most poorly understood demographic phenomena. Numerous physiological, ecological and demographic factors seem to influence it although a unique explanation is lacking. Indeed, some countries have exhibited a trend in the sex ratio at birth over the years. Their sex ratio at birth time series can be modeled with the nonrandom stochastic processes which reflect the interdependency in the subsequent annual observations. This article examines the variations in sex ratio at birth for Nasik region during the period 1901 to 2011. We have compared the sex ratio of rural and urban areas of the region. Further, it was observed that the occurrence of LSCS (Lower Section Caesarean Section) delivery is associated with the decreasing sex ratio. The frequency of LSCS procedure for delivery is highly significant for birth of male child as compare to female child in private hospitals. The comparison is made between private and public hospitals, which shows that proportion of LSCS do not differ significantly gender wise in case of public i.e. government hospitals. The chi square test is carried out for assessing the independence of attributes namely sex and mode of delivery.
