Abortions of girl fetuses in Asia where males are more valuable

Abortion in India is controversially the cause of Gendercide. In many parts of India, daughters are not preferred and hence sex-selective abortion is commonly practiced, resulting in an unnatural male to female population sex ratio due to millions of developing girls selectively being targeted for termination before birth.^[2]

Sex-based birth rate disparity[edit]

Sex ratio at birth in mainland China, males per 100 females, 1980–2010.

The sex ratio at birth (between male and female births) inmainland China reached 117:100 and remained steady between 2000 and 2013, substantially higher than the natural baseline, which ranges between 103:100 and 107:100. It had risen from 108:100 in 1981—at the boundary of the natural baseline—to 111:100 in 1990.^{[42][unreliable source?]} According to a report by theNational Population and Family Planning Commission, there will be 30 million more men than women in 2020, potentially leading to social instability, and courtship-motivated emigration.^[43]
