Rankings

Definition

Males per 100 females in the total population on July 1. UN World Population Prospects estimates for every country and the World.

Values above 100 mean more men than women. Large inflows of male migrant workers raise the ratio well above 100 in some Gulf states. This is the ratio for all ages, not the sex ratio at birth.
