主要统计指标解释

常住人口：指家庭住户成员中，经常在家居住、或者调查期内居住时间超过一半的人员，以及本住户供养的学生。

常住人口是住户收支的调查对象。

可支配收入：指调查户在调查期内获得的、可用于最终消费支出和储蓄的总和，即调查户可以用来自由支配的收入。可支配收入既包括现金，也包括实物收入。按照收入的来源，可支配收入包含四项，分别为：工资性收入、经营净收入、财产净收入和转移净收入。

工资性收入：指就业人员通过各种途径得到的全部劳动报酬和各种福利，包括受雇于单位或个人、从事各种自由职业、兼职和零星劳动得到的全部劳动报酬和福利。

经营净收入：指住户或住户成员从事生产经营活动所获得的净收入，是全部经营收入中扣除经营费用、生产性固定资产折旧和生产税之后得到的净收入。

财产净收入：指住户或住户成员将其所拥有的金融资产、住房等非金融资产和自然资源交由其他机构单位、住户或个人支配而获得的回报并扣除相关的费用之后得到的净收入。

转移净收入：计算公式为：转移净收入=转移性收入-转移性支出

转移性收入：指国家、单位、社会团体对住户的各种经常性转移支付和住户之间的经常性收入转移。

转移性支出：指调查户对国家、单位、住户或个人的经常性或义务性转移支付。包括缴纳的税款、各项社会保障支出、赡养支出、经常性捐赠和赔偿支出以及其他经常转移支出等。

消费支出：指住户用于满足家庭日常生活消费需要的全部支出，包括用于消费品的支出和用于服务性消费的支出。根据用途不同，消费支出可划分为食品烟酒、衣着、居住、生活用品及服务、交通通信、教育文化娱乐、医疗保健、其他用品及服务八大类。根据来源不同，消费支出可划分为现金消费支出、实物消费支出（含自产自用、来自单位、来自政府和其他社会组织）。

恩格尔系数：指食物支出占生活消费总支出的比重。计算公式为：恩格尔系数=食物支出/生活消费总支出×100%。恩格尔系数越大，表示生活越贫困；反之，表示生活越富裕。根据国际经验，恩格尔系数60%以上为贫困，50%-60%为温饱，40%-50%为小康，30%-40%为富裕，30%以下为最富裕。

Number of Dependents per Urban Employee refers to the ratio between number of persons in an urban household and the number of employed persons.

Total Income of Urban Households refers to the sum of wage and salary, net business income, income from properties, and income from transfers of members of the households, excluding income from selling of properties and income from borrowings.

Disposable Income of Urban Households refers to the actual income at the disposal of members of the households which can be used for final consumption, other non-compulsory expenditure and savings. This equals to total income minus income tax, personal contribution to social security and sample household subsidy for keeping diaries. Following formula is used:

Disposable income = total household income - income tax - personal contribution to social security - sample household subsidy for keeping diaries

Consumption Expenditure of Urban Households refers to total expenditure of the sample households for consumption in daily life, including expenditure on eight categories such as food, clothing, household appliances and services, health care and medical services, transport and communications, recreation, education and cultural services, housing, miscellaneous goods and services.
