Sex ratio is defined as the number of females per 1000 males in a population. In India, the 2001 census found a sex ratio of 933 females per 1000 males, a slight increase from 927 in 1991. However, Gujarat saw a decline in its child sex ratio from 923 in 1991 to 883 in 2001 according to the census. The decline in child sex ratio is due to factors like neglect of females resulting in higher mortality, female infanticide, and female feticide which stem from a societal obsession for sons and discrimination against girls.
