Population
Total 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
Urban Population and Rural
Population Urban
population refer to all people residing in cities and towns, while rural
population refer to population other than urban population.
Statistics on urban and rural
population over the years are compiled in line with the regulations of statistical
classification on urban and rural population stipulated by the government, which were in effect at different
times.
Figures
on urban/rural population for the years between the 3 censuses are adjusted in
accordance with the 1990 and 2000 population census data.
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 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 by 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-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
Gross Dependency Ratio also called gross dependency
coefficient, refers to the ratio of non-working-age population to the
working-age population, express in %. Describing in general the number of
non-working-age population that every 100 people at working ages will take care
of, this indicator reflects the basic relation between population and economic
development from the demographic perspective. The gross dependency ratio is
calculated with the following formula:
P0-14+P65+
GDR= ------------- ×100%
P15-64
Where: GDR is the
gross dependency ratio
P0-14 is the population of children
aged 0-14
P65+ is the elderly population
aged 65 and over, and
P15-64 is the working-age population
aged 15-64
Old Dependency Ratio also called old dependency
coefficient, refers to the ratio of the elderly population to the working-age
population, express in %. 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:
P65+
ODR= ------------- ×100%
P15-64
Where: ODR is the
old dependency ratio
P65+ is the elderly population
aged 65 and over, and
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 %. It describes the number of children population that every 100
people at working ages will take care of. The children dependency ratio is
calculated with the following formula:
P0-14
CDR= ------------- ×100%
P15-64
Where: CDR is the
children dependency ratio
P0-14 is the children population
aged 0-14, and
P15-64 is the working-age population
aged 15-64
