Where: Number of births refers to live births, i.e. when a baby has breathed or showed any vital phenomena regardless of the length of pregnancy.

It describes the number of the elderly population that every 100 people at working ages will take care of. Old dependency ratio is one of the indicators reflecting the social implication of population aging from the economic perspective. The old dependency ratio is calculated with the following formula:

P15-64 is the working-age population aged 15-64.
Children Dependency Ratio also called children dependency coefficient, refers to the ratio of the children population to the working-age population, express in percent.
