There are slightly more boys than girls in the world overall, with roughly 102 males for every 100 females in the total population, though this varies by age and region, with more boys at birth (about 105:100) but more women in older age groups because women generally live longer. Estimates suggest over 4.1 billion males and nearly 4.1 billion females as of early 2025, with males making up about 50.27% of the population.
The number of men and women in the world is roughly equal, though men hold a slight lead with 102 men for 100 women (in 2020). More precisely, out of 1,000 people, 504 are men (50.4%) and 496 are women (49.6%).
Gender ratio in the World
As of 2025, there are 4,137,709,238, or 4,138 million, or 4.14 billion, males in the world, representing 50.27% of the world population. The population of females in the world is estimated at 4,093,903,832, or 4,093 million, or 4.09 billion, representing 49.73% of the world population.
It is estimated to be about 1.05 worldwide or within a narrow range from 1.03 to 1.06 males per female at birth. The sex ratio for the entire world population including all ages is approximately 101 males to 100 females as of 2024.
Nationally, there are about 98 men for every 100 women. While more boys than girls are born (about 105 boys for every 100 girls), men die, on average, earlier than women. The sex ratio, defined as the number of men per 100 women, therefore varies significantly by age, as Figure 1 shows.
According to National Family Health Survey, 2020-21 (NFHS-5) India's Sex ratio in 2022 is 1020 females per 1000 males. The sex ratio is 1037 in rural areas and 985 females for every 1000 males in urban areas.
A child's biological sex at birth may not be a 50-50 toss-up, according to a new study from Harvard T.H. Chan School of Public Health. The study, published July 18 in the journal Science Advances, found that birth sex appears to be associated with maternal age, certain genes, and the sexes of older siblings.
In reality, the probability of having a boy is slightly higher: on average, 105 boys are born for every 100 girls. We have no explanation for this fact. In some societies, notably in Asia and Central Europe, the sex ratio at birth exceeds that 105 boys (for 100 girls) biological threshold, rising to approximately 120.
Besides male and female, there are 72 other genders, which include the following: Agender: A person who does not identify themselves with or experience any gender. Agender people are also called null-gender, genderless, gendervoid, or neutral gender.
Globally, the number of males has exceeded the number of females since the mid-1960s. But by 2050, the worldwide sex ratio is expected to even out, according to recently released population projections from the United Nations. As of 2021, there were about 44 million more males than females in the global population.
Worldwide, men outnumber women by some 62 million. More baby boys are born than baby girls, a by-product of enduring natural selection processes. The slight male advantage in numbers at birth disappears progressively during childhood and young adulthood, owing to generally higher male than female mortality.
Gender imbalance
While the difference of gender at birth has been decreasing in the country over the past decade, China still boasts the world's most skewed sex ratio at birth at around 110 males born for every 100 females as of 2023.
Moldova (54.0%), Macao (53.9%), and Latvia (53.7%) follow closely behind. Many of the top-ranking countries are located in Eastern Europe, where factors such as higher male mortality rates and emigration patterns have contributed to the gender imbalance.
Gender is the range of social, psychological, cultural, and behavioral aspects of being a man (or boy), woman (or girl), or third gender. Although gender often corresponds to sex, a transgender person may identify with a gender other than their sex assigned at birth.

The results of the present study revealed that the first stage of labor was slower in women with male fetuses than those who carried female fetuses (Mean duration in female fetuses was 2.4 and it was 3.4 in male fetuses).
While historically, there have been about 105 boys born for every 100 girls worldwide — which creates a “sex ratio at birth” of 1.05 — the share of boy babies has increased in recent decades. 2011 data from the World Bank show the global sex ratio at birth is now 1.07, or 107 boys born for every 100 girls.
Geneticists have discovered that all human embryos start life as females, as do all embryos of mammals. About the 2nd month the fetal tests elaborate enough androgens to offset the maternal estrogens and maleness develops.
Though many men can have children into their 50s and beyond, there are some challenges associated with becoming an older dad. Semen volume, sperm quality, and testosterone production all decrease with each passing year.
Babies are created when a sperm cell (containing 50% of the biological father's DNA) fertilizes an egg (containing 50% of the biological mother's DNA) to create an embryo with a full complement of DNA. A baby's biological gender is determined by the sex chromosomes they inherit.
Herein we report the extraordinary case of a fertile woman with normal ovaries and a predominantly 46,XY ovarian karyotype, who gave birth to a 46,XY female with complete gonadal dysgenesis.
India's sex ratio in 2023 is 1,020 females per 1,000 males. The sex ratio in rural areas is 985 females to 1,000 males, and in urban areas, it's 985 females to 1,000 males. The sex ratio at birth has improved by 15 points from 918 in 2014-15 to 933 in 2022-23.
Construction and repair roles, protective services and technical roles remain overwhelmingly male, while healthcare and teaching not only have few men, but have a declining share of men.
