Gendercide is a term that refers to the elimination of one sex through selective abortion, infanticide, abandonment, and abuse. In most cases the preference is for the male. United Nations specialists estimate that around two hundred million girls are missing in the world today. To give a broad figure, they explain that people who practice gendercide in China and India eliminate more girls than the number of girls born in America each year. All in all, they describe the phenomenon as the largest holocaust in human history. We can see this phenomenon happening in several countries in Asia. As a matter of fact, China and India top the charts for imbalanced sex ratio at birth. They are also the most populous countries in the world. They are followed by Nepal and Vietnam regarding gender selection practice. Other examples are Pakistan and Bangladesh, where they have started using medical technology to determine the sex of the unborn child. In the world, the average birth rate is approximately one hundred and five males for every one hundred females. The natural predominance in the number of males is explained by the fact that they are more susceptible to diseases in the first years of life. Girls are considered healthier and, in general, reach puberty more easily. And when they all reach reproductive age, the ratio is one to one. This ratio becomes a problem when it approaches one hundred and eight boys for every one hundred girls. Beyond this number, it is safe to assume that there are serious problems ahead. When we look at the figures in countries suspected of practicing gendercide, we see rates as high as one hundred and twenty boys per one hundred girls. This numerical imbalance for several years represents...... half of the paper ......ver in recent decades, they have managed to reverse the imbalance. Men of the upper classes will find a partner easier than those of the lower classes. In general, the wealthy in all societies do not have to struggle too much to get married. This is an even stronger reality in regions where there is a shortage of women. Disadvantaged men in rural areas are less likely to find a wife. If the first child is a boy and the gender preference is satisfied, it seems less problematic to have a girl as a second child. If the first children are girls, the pressure to have a boy is greater; so you have more chance to practice gender selection. If you have money and security in your old age, you don't need a child to take care of you. If you can save money, you are less obligated to have a boy because you are financially secured.
