Sex ratio :The sex ratio is the ratio of males to females in the population (normalized to 100). We calculate two sex-ratios: At birth, and in the total population.
Dependency ratio: 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.
