Explanatory Notes on Main Statistical Indicators

 

Total Population  refers to the total number of people alive at a certain poi= nt of time within a given area.

The annual s= tatistics on total population is taken at midnight, the 3l^st of December.<= o:p>

Resident Population=     refers to the populati= on actually living for more than half a year at a place.

Registered Population=     refers to the citizens= who have registered their permanent residence with the public security household register authority of the location where they often live.=

Urban Popula= tion and Rural Population  Urban population refers to all people residing in cities a= nd towns, while rural population refers to population other than urban populat= ion.

Birth Rate (= or Crude Birth Rate) &n= bsp;refers to the ratio of the number of births to the average population (or mid-period population) during a certain period of time (usua= lly a year), expressed in ‰. Birth rate in the chapter refers to annual birth = rate. The following formula is used:

Number of bi= rths in the formula refers to live births, i.e. when a baby has breathed or show= ed any vital phenomena regardless of the length of pregnancy.

Annual avera= ge population is the average of the number of population at the beginning of t= he 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 m= id-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 formul= a is used:

Natural Grow= th 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 avera= ge population (or mid-period population) of the same period, expressed in ‰. = The following formula is applied:

Natural Grow= th Rate of Population =3D Birth Rate-Death Rate

Gross Depend= ency Ratio also called gross dependency coefficient, refers to the ratio of non-working-age popula= tion to the working-age population, express in %. Describing in general the numb= er of non-working-age population that every 100 people at working ages will ta= ke 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:

=

Where: GDR is the gross dependency ratio,

  =         P_{0-14  is} the population of children aged 0-14,

  =         P₆₅+  is the el= derly population aged 65 and over, and

  =         P_15-64 is the working-age population aged 15-64.

Old Dependen= cy Ratio  also called old dependency coefficient, refers to the ratio of the elderly population to the working-age population, express in %. It describes the nu= mber of the elderly population that every 100 people at working ages will take c= are 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:

=

Where: ODR is the old dependency ratio,

  =         P₆₅+  is= the elderly population aged 65 and over, and

  =         P_15-64 is the working-age population aged 15-6= 4.

Children Dependency Ratio also called children dependency coefficient, refers to the ratio of the children population to the working-age population, express in %. It describ= es 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:

=

Where: CDR is the children dependency ratio,

  =         P_{0-14  is} the children population aged 0-14, and

  =         P_15-64 is the working-age population aged 15-64.
