India's sex ratio, among children aged 0-6 years, is alarming. The ratio has declined from 976 females (for every 1000 males) in 1961 to 914 in 2011. Every national census has documented a decline in the ratio, signalling a ubiquitous trend. Preliminary data from the 2011 census have recorded many districts with sex ratios of less than 850. The ratio in urban areas is significantly lower than those in rural parts of the country.
Reports suggest evidence of violence and trafficking of poor women and forced polyandry in some regions with markedly skewed ratios. The overall steep and consistent decline in the ratio mandates serious review.
Sex selection and technology : Medical technology (like amniocentesis and ultrasonography), employed in the prenatal period to diagnose genetic abnormalities, are being misused in India for detecting the sex of the unborn child and subsequently for sex-selection. Female foetuses, thus identified, are aborted.
