Population, female (% of total population)
Research over hundreds of years has consistently found that boys naturally outnumber girls at birth. This increase in the sex ratio is driven largely by births in China, where sex ratios have declined slightly in recent years but remain the highest in the world.
However, disproportionately large shares of baby boys are found in other countries scattered throughout Asia and the Caucasus, as well. Azerbaijan, Armenia, Georgia, South Korea, and the Solomon Islands round out the list of places with the highest sex ratios. India is tied with Macedonia, Montenegro, Papua New Guinea, Samoa, Serbia and Suriname for 7th place, with a ratio of boys born for every girls.
Even while some countries seem to have a disproportionate share of boys, others have particularly high shares of baby girls. While there are still slightly more boys born than girls in these places — which are centered in sub-Saharan Africa — the sex ratios are nonetheless much lower than average. Perhaps the best-known reason relates to the practice of sex-selective abortion , which has been identified in Asia, and in the Caucasus , as well. The ability to determine fetal sex, along with strong son preferences, accounts in large part for the high shares of boys in many countries in these regions.
The desire to limit family size, either due to government regulations as in China, or due to global social and economic changes that have reduced the need for large families, seems to further contribute to sex-selective abortion and a dearth of baby girls.
But this is only one of myriad factors that may be affecting the sex ratio at birth. Some research suggests that the share of newborn boys declines with older parents , and that the high share of girls in Sub-Saharan Africa may be linked to the practice of polygamy multiple wives.
What do these two phenomena have in common? Researchers hypothesize that both situations are associated with less frequent intercourse.
For possible explanations of this association, see this article from the academic journal Human Reproduction. On the opposite end of the spectrum, most research shows that the share of baby boys increases during and after wartime.
And once again, frequency of intercourse is cited as the likely reason, at least in the case of post-war reunions. In some cases, though, wartime is associated with a higher share of girl babies. This may relate to the fact that heightened maternal stress , such as would occur during wartime, can lead to an increased likelihood of a miscarriage which is more likely to occur among male fetuses.
Further evidence of this association between maternal stress and the increased share of girl babies emerges from an analysis of births in the vicinity of the Kobe earthquake in Japan, which showed that the share of females born nine months after that event was significantly higher than would have been expected under normal circumstances.

List of Countries by Sex ratio
In the 80s and 90s, Newsweek Magazine delivered US women the cheery news that they were more likely to be killed by a terrorist than to find a husband after age There were too many women—supposedly—and not enough men, and women were the losers. And, of course, staying single was a horrible fate. You need a few extra boys for balance, because men die earlier. We are learning right now what happens when the sex ratio becomes wildly out of whack, through a huge unintended experiment.
In the human species the ratio between males and females at birth is slightly biased towards the male sex. This means that at birth on average, there are males for every females. Nature provides that the number of newborn males slightly outnumber newborn females because as they grow up, men are at a higher risk of dying than women not only due to sex differentials in natural death rates, but also due to higher risk from external causes accidents, injuries, violence, war casualties. Thus, the sex ratio of total population is expected to equalize. Besides, gender imbalances have been known in human history to cause serious negative consequences for the society in the long run.

The French Institute for Demographic Studies or INED, is a public research institute specialized in population studies that works in partnership with the academic and research communities at national and international levels. With its research units, the Institute promotes communication and exchange within the scientific community and between researchers and the general public while conducting numerous European and international research projects. Nearly people, including 50 tenured, or permanent, researchers and more than 40 doctoral students, work at INED; there are also 40 associate researchers. The Institute has 10 research units, a mixed research unit and 5 research support services, including the Statistical Methods and Surveys departments. With its strong interdisciplinarity and its status as a reference in demography, INED is an active contributor to the development of French research. The Institute is one of the driving forces of major current research projects, such as the Campus Condorcet, which is transforming the landscape of the humanities and social sciences in the Paris region. One distinguishing characteristic of INED is its ability to conduct research studies that cover not just France but a large part of the world. The international scope of the Institute may be seen in its many partnerships with institutions abroad and its active role in the world scientific community. INED researchers have a long tradition of collaboration with their counterparts throughout the world.
Total population of the United States, by gender 2010-2024
Worldwide, there are boy babies born for every girl babies. This skewed ratio is partly due to sex-selective abortion and "gendercide," the killing of female infants, in countries such as China and India where males are more desired. But even discounting those factors, the completely natural male-to-female sex ratio still hovers around , meaning that women are inherently more likely to give birth to boys. Several factors influence whether a sperm containing a Y sex chromosome or one containing an X chromosome will be first to fertilize an egg, including parental ages, their environmental exposure, stress, the stage in the mother's ovulation cycle and even whether she has had children previously; all these forces combine to set the average sex ratio at fertilization at But what good is this built-in bias?
The human sex ratio is the number of males for each female in a population. This is a list of sex ratios by country or region.

Why Are More Boys Born Than Girls?
The human sex ratio is the number of males for each female in a population. Sex ratio above means there are more males than females. Sex ratio below means there are more females than males.
Are there more men or more women in the world?
In anthropology and demography , the human sex ratio is the ratio of males to females in a population. More data are available for humans than for any other species, and the human sex ratio is more studied than that of any other species, but interpreting these statistics can be difficult. Like most sexual species, the sex ratio in humans is close to
