In anthropology and demography, the human sex ratio is the sex ratio for Homo sapiens (i.e., the ratio of males to females in a population). Like most sexual species, the sex ratio is approximately 1:1. In humans the secondary sex ratio (i.e., at birth) is commonly assumed to be 105 boys to 100 girls, an assumption that is a subject of debate in the scientific community. The sex ratio for the entire world population is 101 males to 100 females.
