The gender ratio in the world in 2021 was 101.7 men per 100 women. There have been more women than men before 1957. Over the years, the ratio of men to women has increased: from 99.7 men per 100 women in 1950 to a maximum of 101.7 men in 2011. The ratio is expected to decrease to 100.3 in 2100.
However, in most countries, there are more women than men. Two most populous countries China and India have higher male populations by a notable margin. These countries determine the prevalence of the number of men in the world.
In terms of age groups among children and young people, the most pronounced gender inequality in favor of the male sex is observed among teenagers. Thus, in 2021, there were 106.3 boys for every 100 girls from birth to 4 years old, 106.6 - from 5 to 9 years old, 106.9 - from 10 to 14 years old, 107.1 - from 15 to 19 years old. Among young people, the situation was as follows: in the age group from 20 to 24 years old, there were 106.7 guys per 100 girls, from 25 to 29 years old - 106.2.
The older the group, the faster the predominance of men over women decreases, and so on up to 50 years. From this point on, the number of women begins to prevail over the number of men. So, in 2021, for 100 women in the age category from 50 to 54 years there were 99.8 men, from 60 to 64 years - 95.4 men, from 70 to 74 years - 86.1 men, from 80 to 84 years - 70.4 men.
The most noticeable difference is observed in extreme old age: in the category of older people from 85 to 89 years old in 2021, there were 60.7 men per 100 women, from 90 to 94 years old - 48.7 men, from 95 to 99 years old - 36.7 men, over 100 years - only 27.8 men.
