This map shows worldwide human sex ratio at birth. Sex ratio is the number of males for each female.
Current world sex ratio at birth: 1.07:1 male(s)/female (107 boys to 100 girls)
Sex ratio at birth has recently emerged as an indicator of certain kinds of sex discrimination in some countries. For instance, high sex ratios at birth in some Asian countries are now attributed to sex-selective abortion and infanticide due to a strong preference for sons. This will affect future marriage patterns and fertility patterns. Eventually, it could cause unrest among young adult males who are unable to find partners.
