Sex Ratio: There are Only 85 Men for Each 100 Women in Russia


The sex ratio is the ratio of males to females in a population. In most sexually reproducing species, the ratio tends to be 1:1. This tendency is explained by Fisher's principle. For various reasons, however, many species deviate from anything like an even sex ratio, either periodically or permanently.

  • India: 108 
  • China: 106 
  • Turkey: 102 
  • Indonesia: 100 
  • Brazil: 98 
  • UK: 98
