In the human species the ratio between males and females at birth is slightly biased towards the male sex. The natural “sex ratio at birth” is often considered to be around 105. This means that at birth on average, there are 105 males for every 100 females. Nature provides that the number of newborn males slightly outnumber newborn females because as they grow up, men are at a higher risk of dying than women not only due to sex differentials in natural death rates, but also due to higher risk from external causes (accidents, injuries, violence, war casualties). Thus, the sex ratio of total population is expected to equalize. Instead if a country’s population sex ratio does not equalize or rather exceeds the 105-threshold, it means societies with a dominating preference for male child tend to intervene in nature and reduce the number of born girl child by sex-selective abortion and infanticide. The present study is related to all districts of Haryana from 1991-2011. Haryana is one of the worst states in context of child sex ratio. The child sex ratio of Haryana state was improved from 819 to 830 (11 points) from 2001 to 2011 census that was declined points 23 from 1991 to 2011.
