Explanatory Notes on Main Statistical Indicators

 

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.

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 . 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 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 . 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 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 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:

 

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:

 

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:

 

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.

Resident Population   According to survey of population, it includes the following main items: 1) population who reside in this township or town (sub-district) with residence registered in this area, or population who have residence registered in this township or town (sub-district) but have been away from this area for less than half a year; 2) population having actually resided in this township or town (sub-district) for over half a year with residence registered in other area; 3) population residing in this townships or towns (sub-district) with residence not registered; 4) population with residence registered in this township or town (sub-district) who work or study abroad.

The Illerate Population   refers to those over 15 years of age who have inability to read or write, or can read or write only a few words.

Illiteracy Rate   refers to the percentage of the illiterate population in the total population above 15 years of age.

Urban Population and Rural Population  Urban population refers to all people residing in the urban and township areas, while rural population refers 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.

Employees   refer to the persons aged 16 and over who are engaged in social working and receive remuneration payment or earn business income. This indicator reflects the actual utilization of total labor force during a certain period of time and is often used for the research on China's economic affairs and national power.

Staff and Workers   refer to persons working in, and receive payment from units of state ownership, collective ownership, joint ownership, share holding ownership, foreign ownership, and ownership by entrepreneurs from Hong Kong, Macao, and Taiwan, and other types of ownership and their affiliated units(excluding private enterprises and owners of self-employed). They exclude: retirees; re-employed retirees; foreigners and persons from Hong Kong, Macao and Taiwan who work in urban units; 8) other persons not to be included by relevant regulations. (Data of 1998 and afterward refer to fully employed staff and workers. Other related statistics such as total wage bill and average wage are adjusted since 1998 accordingly).

State-owned Units   refer to economic units whose assets are owned by the state. Included are non-corporation units registered according to Regulation of the Peoples Republic of China on the Registration of Enterprises and Corporations, state organs, institutions and social organizations at the central and local levels.

Total Wages of Bill   refers to total remuneration payment to staff and workers in various units during a certain period of time. The calculation of total wages is based on the total remuneration payment to the staff and workers. Therefore, all the wages and salaries and other payments to staff and workers are included in the total wage bill regardless of  sources, reckoning the cost of production or not, category, listing as items of premium taxation or not, and forms, paying in cash or in kind.

Average Earning of Employees=Total Earning of Employees at Reference Period/Average Number of Employees at Reference Period

Among whom, the urban resident population without employment experience shall be registered at the place of household registration; the off-farm workers and other persons with the household registration at other places who have been employed for 6 consecutive months may be registered at the place of their usual residence.

  Registered Unemployment Rate in Urban Areas   refers to the ratio of the number of the registered unemployed persons at the end of the reference period to the sum of total employment and the number of the registered unemployed persons at the end of the reference period. The formula is as the follows:

Registered urban unemployment rate = number of registered urban unemployed persons at the end of reference period / (total employment+ number of registered urban unemployed persons at the end of reference period) 100%
