In contemporary India, due to the practice of female infanticide over several generations, the male to female gender ratio has been heavily skewed, and the country has more men than women. As a result, many men complain that they can't find a wife.
The male-skew in India's sex ratio has increased significantly since the early 20th century. In 1901 there were 3.2 million fewer women than men in India, but by the 2001 Census the disparity had increased by more than a factor of 10, to 35 million.This increase has been variously attributed to female infanticide, selective abortions (aided by increasing access to prenatal sex discernment procedures), and female child neglect. It has been suggested that the motivation for this selection against female children is due to the lower status and perceived usefulness of women in India's patriarchal society.
Similarly, the practice of polygamy has the effect of creating more lifelong celibate males, since the pool of single women for marriage is reduced.
On the other hand, polygamy is useful when there is a gender imbalance in which women outnumber men, and polyandry is forbidden in Hinduism.
Does any Hindu scripture talk about the sociological ill-effects of polygamy?
