Explanation
|
| 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
midnight, the 3lst of December, not including residents
in Taiwan province, Chinese compatriots in Hong Kong
and Macao and overseas Chinese.
|
| Urban Population and Rural Population
| There are three definitions.
(1) The first definition (by the administrative system):
Urban Population refers to total population under the
jurisdiction of city and the population of towns under
the jurisdiction of counties.
Rural Population refers to total population of townships
under the jurisdiction of counties.
(2) The second definition (by the permanent residence):
Urban Population refers to total population of districts
under the jurisdiction of a city with district establishment,
the population of street committees under the jurisdiction
of a city without district establishment, population
of resident-committees of towns under the jurisdiction
of a city without district establishment, and the of
resident-committees of towns under the jurisdiction
of a county.
Rural Population refers to total population except urban
population.
(3) The third definition (based on the statistical classification):
Urban Population/ Rural Population are classified according
to the Regulation of Statistics Classification on Urban
and Rural Population (Draft), formulated by the National
Bureau of Statistics in 1999.
Data from 1952 to 1980 are the figures according to
the first definition. Data from 1982 to 1999 are the
figures according to the second definition. Urban/rural
population in 2000 is the figure according to the third
definition.

| 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) which
is often expressed in ¡ë. Birth rate in the chapter refers
to annual birth rate. The following formula is used:
Birth Rate = Number of Births/Average Number of Population¡Á1000¡ë
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-period population)
during a certain period of time (usually a year) which
is often expressed in ¡ë. 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¡Á1000¡ë
|
| 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 which is often expressed in ¡ë. The following
formulas are applied:
Natural Growth of Population = (Number of Births-Number
of Deaths)/Average Number of Population¡Á1000
Natural Growth Rate of Population = Birth Rate-Death
Rate
|
| Total Dependency Ratio
| refers to the ratio of number of dependents
to the total population aged 15-64, the number of dependents
being population aged 0-14 and population aged 65 and
over. The total dependency ratio is calculated as follows:
Total Dependency Ratio = Number of Dependents/Population
Aged 15-64¡Á100%
|
| The Aged Dependency Ratio
| refers to the ratio of the number of the
aged population to the total population aged 15-64,
the aged being population aged 65 and over. The aged
dependency ratio is calculated as follows:
The Aged Dependency Ratio = Number of the Aged Population/
Population Aged 15-64¡Á100%
|
| The Juvenile and Children Dependency Ratio
| refers to the ratio of the number of the
juvenile and children to the total population aged 15-64,
the juvenile and children being population aged 0-14.
The juvenile and children dependency ratio is calculated
as follows:
The Juvenile and Children Dependency Ratio = Number
of Juvenile and Children/ Population Aged 15-64¡Á100%
