The sex ratio is 107 males to 100 females, based on an estimated population of 7.17 billion people as of July 2014. Therefore, there are about 3.7 billion males in the world, and about 9.56 million of them are ages 14 and under.

The natural sex ratio is 105 to 100. However, gender selection for males in patriarchal societies has altered birth rates through the abortion of girls, creating an unnatural imbalance in sexes. China and India have had sex ratios at birth as high as 120 to 100. Though the worldwide sex ratio only seems slightly out of balance, some countries' adult sex ratios are as high as 274 to 100 between the ages of 16 to 24.
