A sex ratio is the ratio of female to males in a population. As explained by Fisher's principle, for evolutionary reasons this is typically about 1:1 in species which reproduce sexually. However, many species deviate from an even sex ratio, either periodically or permanently.
Sex ratio is defined as the number of females per 1000 males in a given population. In a society that has males and females equal in number, the sex ratio is 1:1 or 1000 females for every 1000 males.
