Indicators of Income Level and Quality of Life of Residents
[Indicators of Income Level of Residents]
Total Income of Urban Residents Refers to the actual income of all the surveyed urban residents' households, including regular or fixed income and one-time income. It includes residents' labor income, net income from private and individual operators, property income (interest, dividends, rent, etc.), and transfer income (including pensions, price subsidies, alimony income, gift income, etc.). It does not include borrowing income, such as withdrawing bank deposits, borrowing from friends and relatives, recovering loaned money and other kinds of temporary receipts.
Urban residents' disposable income Refers to the actual income remaining after paying personal income tax, production tax and other current transfer expenditures for a certain period of time.
Disposable Income = Actual Income - Personal Income Tax - Property Tax - Current Transfer Expenditures
Disposable Income Per Capita of Urban Residents Reflects the average income level of urban residents. It is calculated on the basis of the sum of the disposable incomes of the surveyed households obtained from the Urban Household Sample Survey, averaged over the population of the surveyed households.
Total household income of rural residents includes basic income, transfer income and property income. Basic income refers to the remuneration income of farmers and family business income; transfer income includes the income sent back and brought back by the foreign population, gift income, relief income, pension, pension, incentive income, compensation income for land expropriation, insurance compensation, etc.; and property income includes interest and dividend income.
The net income of rural households refers to the part of the total income of households of permanent residents in rural areas that can be used directly for investment in productive and unproductive construction, living consumption and savings, after deducting the expenses of engaging in production and unproductive business, paying taxes and handing over the amount of the contracted collective tasks. The net income of rural households includes both productive and unproductive business income, including non-business income such as the income sent back by the population outside the country and the State financial relief and subsidies of various kinds; it includes both monetary income and income in kind from self-production and self-consumption. However, it does not include income from borrowing from banks, credit unions and friends and relatives.
Per capita net income of rural households Reflects the average income level of rural residents, which is calculated on the basis of the sum of the net incomes of the surveyed households and the population of the surveyed households obtained from the Rural Household Sample Survey.
The Gini coefficient reflects the average level of income of residents. It is based on the correspondence between the cumulative percentage of income (vertical coordinate) and the cumulative percentage of population (horizontal coordinate), depicting a curve called the Lorenz curve. The area between the Lorenz curve and the 45-degree line is denoted by A, and the area between the Lorenz curve and the horizontal coordinate is denoted by B. The ratio of A to A+B is the Gini coefficient; if A+B = 0.5, the Gini coefficient = 2A.
It is generally believed that the Gini coefficient of less than 0.2 indicates absolute average; between 0.2 and 0.3 indicates relatively average; and between 0.3 and 0.4 indicates reasonable; Above 0.4 indicates an excessive gap. Greater than 0.6 indicates the existence of serious income inequality and polarization of the rich and the poor, while less than 0.2 means that there is a tendency towards egalitarianism in income distribution.
At present, China calculates three kinds of Gini coefficients: the Gini coefficient for rural residents, the Gini coefficient for urban residents, and the Gini coefficient for the whole country.
[Indicators of residents' consumption level and quality of life]
Consumption Expenditure of Urban Residents' Households Refers to all the expenditures of the surveyed urban residents' households for daily life, including expenditures on the purchase of commodities and non-commodity expenditures on cultural life and services. It excludes confiscated and lost money and various taxes paid (such as personal income tax, license tax, property tax, etc.), as well as expenses incurred by individual workers in the course of production and business.
Expenditure on the purchase of commodities by urban households This refers to all expenditures on the purchase of commodities by surveyed urban households for their own use or as gifts for relatives and friends, including expenditures on the purchase of all kinds of commodities from stores, factories, catering industries, workplace canteens, bazaars, and directly from farmers. Expenditures on commodities are divided into the following eight categories: food; clothing; household equipment and goods and services; medical care; transportation and communication; recreation, education and cultural services; housing; and miscellaneous goods and services.
Rural Household Living Consumption Expenditure Refers to all the expenditures of rural resident households for daily life, including monetary and physical consumption for food, clothing, housing, cooking, and other living consumption and cultural and living services, and it is an important indicator for reflecting and researching the actual level of living consumption of farmers' households.
The Engel coefficient is an indicator of the standard of living of the population, which refers to the proportion of the population's food expenditure to all living consumption expenditure. The larger the coefficient, the lower the standard of living of the population. On the other hand, it indicates a higher standard of living. It can be calculated separately for urban and rural areas.
Engel's Coefficient = Food Expenditure / Consumption Expenditure x 100%
Living Area Per Capita of Urban and Rural Residents Reflecting the living standard of urban and rural residents, it is obtained by dividing the living area of the family house by the resident population of the family. The living area refers only to the indoor area of the living room, excluding the area occupied by the structure of the house and auxiliary areas such as the kitchen and bathroom.
The per capita housing area of urban and rural residents is calculated by dividing the living area of the family housing by the resident population of the family.
[Overview of towns and cities, indicators of quality of life of urban residents]
The production capacity of tap water at the end of the year The actual production capacity of tap water plants managed by the urban construction department and social units with their own water sources at the end of the year in terms of abstraction, purification, delivery, and outgoing trunk water pipelines.
Length of water supply pipes at the end of the year Refers to the length of all pipes between the water delivery pump and the water meter of the user.
Total annual water supply Refers to the total annual water supply of public waterworks and social units with their own water sources, including the effective water supply and loss of water.
Domestic water consumption Refers to the amount of water used by residents in their daily lives and public ****welfare facilities, including the amount of water used by residents, eating and drinking establishments, hotels, hospitals, barbershops, baths, laundries, swimming pools, stores, schools, institutions, and military units.
Urban Population Water Penetration Rate The ratio of the number of non-agricultural people using water in the city (excluding temporary and floating population) to the total non-agricultural population in the city. The formula is:
Water Use Penetration Rate=Number of Non-Agricultural Population Using Water in Cities / Number of Non-Agricultural Population in Cities×100%

Length of gas pipeline Refers to the entire length of the pipeline from the outlet of compressor, blower and storage tank to the gas meter of the user.
Total annual gas supply Refers to the total amount of gas sold to various types of users throughout the year, including industrial use, household use and other use.
Urban Gas Penetration Rate The ratio of the number of urban non-agricultural population using gas (including artificial gas, liquefied petroleum gas and natural gas) (excluding temporary population and floating population) to the total urban non-agricultural population. The formula is:
Urban gas penetration rate = the number of non-agricultural population using gas in the city / the total number of non-agricultural population in the city × 100%
