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.

Data taken from The World Factbook (2011). It shows the male to female sex ratio as estimated by United States' CIA. However, there are differences between the estimates by The World Factbook and numbers reported by the census offices of respective countries. For example, The World Factbook in 2011 reported Switzerland's sex ratio at birth as 1.05, while Switzerland's Federal Office of Statistics in 2011 reported Switzerland's sex ratio at birth as 1.07 per its birth records census data. Similar differences between estimates by "The World Factbook" and census numbers from birth records are known for Sweden, Norway, Ireland, India and Japan.

A ratio above 1 means there are more males than females, while a ratio below 1 means there are more females than males. A ratio of 1 means there are equal numbers of females and males.
