certain period of time(usually a year) which is often expressed in‰. The following formula is used:
Number
of births refers to live births i.e. the births when babies had showed any
vital phenomena regardless of the length of pregnancy.
Annual
Average Number of Population is the average of the number of population at the

year population) during a certain period of time (usually a year) which is
often expressed in‰. The following formula is used:
Death
Rate umber of Deaths
Number
of Deaths/ Annual Average Number of Population
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 formulas are applied:
Natural
Growth of Population
Number of
Births-Number of Deaths / Average Number of Population
Natural
Growth Rate of Population=Birth Rate-Death Rate
