Are there more men or more women in the world?

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 2015). More precisely, out of 1,000 people, 504 are men (50.4%) and 496 are women (49.6%). For every 100 girls, 107 boys are born, but males have a higher risk of dying than females, both in childhood and at adult ages.

So at a certain age, the numbers of men and women even out. In France this occurs at age 25 (in 2015). Beyond this age, women outnumber men and the numerical difference between the two sexes increases with age. In France, eight centenarians in ten are women (in 2015).
