Population
refers to the total number of people alive at a certain point of time
within a given area��
The annual statistics on total population is
taken at midnight, the 3lst of December, not including residents in
Usual
Resident Population refers to the population that actually reside in a place, usually longer
than half a year.
Urban
Population and Rural Population Urban population
refers to all people residing in cities and towns, while rural population
refers to population other than urban population.
Birth
Rate or (Crude Birth Rate) refers to the ratio of the number of births to the average population (or
mid-period population) during a certain period of time (usually a year),
expressed in ��. Birth rate in the chapter refers to annual birth rate. The
following formula is used:
Birth Rate��(Number of Births/Average Number of Population)��1000��
Number of births in the formula refers to
live births, i.e. when a baby has breathed or showed any vital phenomena
regardless of the length of pregnancy.
Annual average 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 by the mid-year population.
Death

the number of deaths to the average population (or mid-period population)
during a certain period of time (usually a year), expressed in ��. Death rate in
the chapter refers to annual death rate. The following formula is used:
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-period population) of the same period, expressed in ��. The following
formula is applied:
Natural Growth Rate of Population��(Number of Births-Number of Deaths)/Average Number of Population��1000��
Natural Growth Rate of Population��Birth Rate��Death Rate
