sex ratios  

Définition

  • The sex ratio (SR) is the most popular index of sex composition used in demographic and other scholarly analyses; it is defined as the number of males per 100 females: An SR above 100 indicates an excess of males, and an SR below 100 indicates an excess of females. In some countries including India, Iran, Pakistan, and Saudi Arabia, the SR is calculated as the number of females per 100 males, but the SR formula shown above is used by most demographers and international bodies such as the United Nations.
