Brith Rate= (Number of Births/Annual Average Number of Population)×1000‰
Number of births refers to live births i.e. the births when babies had showed any vital phenomena regardless of the length of pregnancy.

Death Rate =(Number of Deaths/ Annual Average Number of Population)×1000‰
Natural Growth Rate of Population refers to the ratio of natural increase in population(number of births minus number of deaths)in a certain period of time(usually a year)to the average population(or mid year population)of the same period which is often expressed in‰. The following formula is applied:
Natural Growth Rate of Population= [(Number of Births-Number of Deaths )/ Average Number of Population]×1000‰
