Hello, Milo. It's believed that the ratio of boys to girls, at birth, is 1.07 : 1. To put it another way, about 107 boys will be born for every 100 girls. However, the world population is different; 101 men for every 100 women. I suppose this means we dudes tend to die faster through various means. Consider the increased longevity of most women; average life expectancy for men is 76, and for women it's 81. Hmm, I'd be interested in researching the topic further. Regardless, I hope this helped!
