There are approximately 4.1 billion girls/women on Earth, making up nearly half the global population (around 49.7%), though precise numbers vary slightly by source and year, with estimates around 2024-2025 placing females at roughly 49.7% of the total 8.1+ billion people, with more males born but women often living longer. The term "universe" is generally limited to Earth's population in these statistics, as numbers for other planets aren't known.
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.
Cute girl,lovely girl,sexy girl,hot girl, angry girl,beautiful girl, Innocent girl,smart girl,shy girl! God knows how many adjectives do we need to define a girl? And seriosuly no two girls are alike.
In humans, the natural sex ratio at birth is slightly biased towards the male sex. 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.
A century ago, there were less than two years between men's and women's life expectancies in the United States. Today, that gender gap has almost tripled, with men dying 5.3 years earlier than women in 2023.
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).
A tomboy is a girl or young woman who generally expresses masculine traits. Such traits may include wearing androgynous or unfeminine clothing and engaging in activities and behaviors traditionally associated with boys or men.
Distinct from the well-known Alpha and Beta, the Sigma Female is often described as the rarest type of woman, making up just 0.1% of the population. But what exactly makes a Sigma Female stand out? Sigma Females are known for their independence and self-reliance.
During early development the gonads of the fetus remain undifferentiated; that is, all fetal genitalia are the same and are phenotypically female. After approximately 6 to 7 weeks of gestation, however, the expression of a gene on the Y chromosome induces changes that result in the development of the testes.
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.
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.
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.
Based on a comparison of 174 countries in 2024, Russia ranked the highest in female population as a percentage of total population with 58.2% followed by Belarus and Bulgaria.
The spontaneous assumption that a pregnant woman is just as likely to give birth to a girl as she is to give birth to a boy. In reality, the probability of having a boy is slightly higher: on average, 105 boys are born for every 100 girls.
The probability of conceiving and birthing a male or female child is theoretically about 50-50. This is because at least initially, equal proportions of sperm cells carry X and Y sex chromosomes, which are a major — though certainly not the only — factor determining sexual development in humans.
Unsurprisingly, February 29 th is the least common birthday. Because Leap Day only rolls around every four years, there's only a 1/1,461 chance of being born on this day (versus 1/365 for any other given day).
A sigma female is independent, loyal, and assertive.
“Sigma” is a personality archetype that was created to contrast the alpha and beta personality types. Sigma women don't care about peer pressure or societal norms: they do what they want when they want to.
Rare Baby Girl Names
No, "tomboy" isn't inherently LGBTQ+, but it describes a gender expression (masculine-leaning for someone female-aligned) that often overlaps with queer identities, especially in sapphic communities where terms like butch are used, and it can be a stepping stone for some people to realize they are non-binary or trans. A tomboy can be straight, queer, cisgender, or trans; the label focuses on gender expression (clothing, activities) rather than sexual orientation or core gender identity, but it's increasingly embraced by the LGBTQ+ community to challenge rigid gender norms, say INTO article and Taimi article.
“For younger kids, it's very common to explore different gender expressions. A lot of kids do this during dress-up play or pretend play. It may mean that they're exploring their gender identity as well, but a lot of times, they're just exploring expression and seeing how these different things feel.”
Tomgirls are also the counterpart to tomboys, females/girls who express themselves in a masculine/manly manner. Historically, being a tomgirl has been associated with being gay, but this is now recognized as inaccurate and a stereotype.
In fact, researchers say that if the mom-to-be is carrying a baby girl, she can expect heightened inflammation in her body that will cause her more discomfort and possibly greater exposure to disease. So this could explain the extra aches and pains and even morning sickness many moms deal with while pregnant.
The energy intake of pregnant women is about 10% higher when they are carrying a boy rather than a girl. Our findings support the hypothesis that women carrying male rather than female embryos may have higher energy requirements and that male embryos may be more susceptible to energy restriction.
Physical differences are undeniable — baby boys have higher levels of testosterone than girls and lower levels of serotonin, which causes them to be more easily stressed and harder to calm down.
