List of sovereign states by sex ratio

The human sex ratio is the comparative number of males with respect to each female in a population.

This is a list of sex ratios by country or region.

It shows the male to female sex ratio by the Central Intelligence Agency of the United States.

If there is a discrepancy between The World Factbook and a country's census data, the latter may be used instead.

A ratio of 1 means there are equal numbers of males and females.
