title: The role of secondary sex ratios in the declining sex ratio of India.
abstract: The sex ratio in India has been gradually declining since the beginning of this century during the intercensus period of 1981-91, this ratio declined from 933 to 929. In the past the difference in sex ratios was wholly attributed to higher mortality amongst the females. However date for the years 1990-92 on secondary sex ratios i.e. sex ratio at birth presented in this paper suggest that the difference in sex ratio can also be attributed to a statistically significant higher number of males being born most probably as a result of selective abortion of female fetuses.
