Explanatory Notes on Major Statistical Indicators
【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 ‰. 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-period 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 the average population (or mid-period 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
【Economically Active Population】 refers to the population aged 16 and over who are capable to work, are participating in or willing to participate in economic activities, including employed persons and unemployed persons.
【Employees of the Unit】 refers to the personnel who work in the government offices,

【Full Employed Staff and Workers】refers to the employees who work for the unit and get paid by it, including those who are leave because of illness, injuries and pregnancies.
【Average Wage of Staff and Workers】refers to the average wage in money terms per person during a certain period of time for staff and workers in enterprises, institutions, and government agencies, which reflects the general level of wage income during a certain period of time and is calculated as follows:
Average Wage of Staff and Workers = Total Wages of Staff and Workers in Reference Period/Average Number of Staff and Workers in Reference Period.
【Specialized Technical Personnel】refer to the professional technology and administrative personnel.

【Registered Urban Unemployment Rate】Registered unemployment rate in urban areas refers to the ratio of the number of the registered unemployed persons to the sum of the number of employed persons and the registered unemployed persons . The formula is as follows:
Registered urban unemployment rate = number of registered urban unemployed persons÷(number of urban employed persons + number of registered urban unemployed persons) × 100%.
