Sex-selective abortion and infanticide


Sex-selective abortion is the practice of terminating a pregnancy based upon the predicted sex of the infant. The selective abortion of female fetuses is most common in areas where cultural norms value male children over female children, especially in parts of East Asia and South Asia (particularly in countries such as People's Republic of China, India and Pakistan), as well as in the Caucasus, and Western Balkans.

Sex-selective abortion affects the human sex ratio—the relative number of males to females in a given age group, with China and India, the two most populous countries of the world, having unbalanced gender ratios. Studies and reports focusing on sex-selective abortion are predominantly statistical; they assume that birth sex ratio—the overall ratio of boys and girls at birth for a regional population, is an indicator of sex-selective abortion. This assumption has been questioned by some scholars.

Scholars who support the assumption, suggest that the expected birth sex ratio range is 103 to 107 males to females at birth. Countries considered to have significant practices of sex-selective abortion are those with birth sex ratios of 108 and above (selective abortion of females), and 102 and below (selective abortion of males).

Sex-selective abortion affects the human sex ratio—the relative number of males to females in a given age group. Studies and reports that discuss sex-selective abortion are based on the assumption that birth sex ratio—the overall ratio of boys and girls at birth for a regional population, is an indicator of sex-selective abortion.

The natural human sex ratio at birth was estimated, in a 2002 study, to be close to 106 boys to 100 girls. Human sex ratio at birth that is significantly different from 106 is often assumed to be correlated to the prevalence and scale of sex-selective abortion. This assumption is controversial, and a subject of continuing scientific studies.

One school of scholars suggest that any birth sex ratio of boys to girls that is outside of the normal 105-107 range, necessarily implies sex-selective abortion. These scholars claim that both the sex ratio at birth and the population sex ratio are remarkably constant in human populations. Significant deviations in birth sex ratios from the normal range can only be explained by manipulation, that is sex-selective abortion.
