How is *** ratio calculated

*** ratio is the ratio of males to females in a population. That is, it is the proportion of males in a population. As per Fisher’s principle, this ratio is 1:1 for most sexually reproducing species. The human *** ratio is, for obvious reasons, studied more than the ratio for any other species. It is of major importance to the studies of anthropology and demography. The *** ratio at birth for the world is 107:100. This is because of the higher foetal mortality in females. The *** ratio is 943 in India as per the 2011 census. That is, there are 943 females for every 1000 males. A skewed *** ratio which is not in favour of women is a dangerous sign because it indicates a higher female foetal mortality rate. This is a particular problem in certain states where there is active *** selection by parents and girls are killed even before they are born. Haryana has the lowest *** ratio in India among states at 879 girls for 1000 boys. Decreasing *** ratios pose dangers for the future female population in the country.
