List of countries by sex ratio


The human sex ratio is the number of males for each female in a population. This is a list of sex ratios by country or region.

Methodology

The table's data is from The World Factbook unless noted otherwise. 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 above 1, for example 1.1, means there are 1.1 males for every 1 female. A ratio below 1, for example 0.8, means there are 0.8 males for every 1 female. A ratio of 1 means there are equal numbers of males and females.
