The ratio is normalized to refer to a standard unit of people, usually 100 persons. We calculate two sex-ratios: At birth, and in the sex determination in drosophila and man will live forever population. The sex ratio at birth is fairly standard, around 105.

Due to higher mortality among males, the sex ratio in the total population switches to 95-97. Sex ratio for total population: 101. Sex ratio for population 15-49, with heavy male outmigration: 99. EXAMPLE: You have been asked to determine if there may be a problem with underreporting of female births in Rajasthan, India. The birth registers for the district show 2456 male births and 2102 female births.

Dependency ratios- This ratio quantifies the number of persons in a population who are not economically active for every 100 economically active persons in that population. It can be calculated by dividing the population 0-14 years and 65 years and older by the population that is in the 15-64 year age group. Example: A community has 41,650 children under age 14 and 6,800 persons age 65 and over. You can also use the percentages from age distributions. Child-woman ratio- This ratio, the CWR, the ratio of children under 5 per 1000 women of reproductive age.
