Where did 4,000,000 females go? Apparently in India, having a baby girl is financial suicide, because when that girl grows up and marries the parents must provide the grooms family with a healthy and expensive dowry. As a result, Indian folk are selectively choosing to abort female fetuses or worse, sometimes killing female babies.
The phenomenon of female infanticide is as old as many cultures, and has likely accounted for millions of gender-selective deaths throughout history. It remains a critical concern in a number of "Third World" countries today, notably the two most populous countries on earth, China and India. In all cases, specifically female infanticide reflects the low status accorded to women in most parts of the world; it is arguably the most brutal and destructive manifestation of the anti-female bias that pervades "patriarchal" societies. It is closely linked to the phenomena of sex-selective abortion, which targets female fetuses almost exclusively, and neglect of girl children.
In India this practice is so widespread that it has resulted in a real shortage of available females. Many men are unable to find a woman to marry and thus remain unmarried.
It is estimated that the female population is 4,000,000 shy of what it would naturally be if this practice did not exist. Other estimates are less drastic. Gendercide Watch is aware of no overall statistics on the numbers of girls who die annually from infanticide. Calculations are further clouded by the unreliability and ambiguity of much of the data. Nonetheless, a minimum estimate would place the casualties in the the hundreds of thousands, especially when one takes into consideration that the phenomenon is most prevalent in the world's two most populous countries. Sex-selective abortions likely account for an even higher number of "missing" girls.
According to Peter Stockland, "Years of population engineering, including virtual extermination of 'surplus' baby girls, has created a nightmarish imbalance in China's male and female populations."
Interestingly, infanticide is a crime overwhelmingly committed by women, both in the Third and First Worlds. In India, ultrasounds to determine the sex of an unborn fetus for the purpose of ending the pregnancy are illegal yet still commonly practiced by doctors. Apparently, the laws are not routinely enforced. It is also not uncommon for a doctor to recommend terminating an unwanted female fetus. Most of these doctors are men.
