ratio of male and female in the world
Human sex ratio Like most sexual species, the sex ratio in humans is approximately 1:1. Due to higher female fetal mortality,[2] the sex ratio at birth worldwide is commonly thought to be 107 boys to 100 girls,[3] although this value is subject to debate in the scientific community. The sex ratio for the entire world population is 101 males to 100 females.[4] Depending upon which definition is used, between 0.1% and 1.7% of live births are intersex.[5][6]
