Birth Rate or (Crude Birth Rate) refers to the ratio of the number of
births to the average population during a 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 beginning of the year and that at the end of
the year. Sometimes it is substituted for with the mid year population.
Death Rate(or Crude Death Rate) refers to the ratio of the number of
deaths to the average population (or mid 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
Employed Population refers to population aged 15 or over engaging in
social labour which generates income.
