Chinese Household Income Project, 2002

The purpose of this project was to measure and estimate the distribution of personal income and related economic factors in both rural and urban areas of the People's Republic of China. The principal investigators based their definition of income on cash payments and on a broad range of additional components. Data were collected through a series of questionnaire-based interviews conducted in rural and urban areas at the end of 2002.
There are ten separate datasets. The first four datasets were derived from the urban questionnaire. The first contains data about individuals living in urban areas. The second contains data about urban households. The third contains individual-level economic variables copied from the initial urban interview form. The fourth contains household-level economic variables copied from the initial urban interview form. The fifth dataset contains village-level data, which was obtained by interviewing village leaders. The sixth contains data about individuals living in rural areas. The seventh contains data about rural households, as well as most of the data from a social network questionnaire which was presented to rural households. The eighth contains the rest of the data from the social network questionnaire and is specifically about the activities of rural school-age children. The ninth dataset contains data about individuals who have migrated from rural to urban areas, and the tenth dataset contains data about rural-urban migrant households.
Dataset 1 contains 151 variables and 20,632 cases (individual urban household members). Dataset 2 contains 88 variables and 6,835 cases (urban households). Dataset 3 contains 44 variables and 27,818 cases, at least 6,835 of which are empty cases used to separate households in the file. The remaining cases from dataset 3 match those in dataset 1. Dataset 4 contains 212 variables and 6,835 cases, which match those in dataset 2. Dataset 5 contains 259 variables and 961 cases (villages). Dataset 6 contains 84 variables and 37,969 cases (individual rural household members). Dataset 7 contains 449 variables and 9,200 cases (rural households). Dataset 8 contains 38 variables and 8,121 cases (individual school-age children). Dataset 9 contains 76 variables and 5,327 cases (individual rural-urban migrant household members). Dataset 10 contains 129 variables and 2,000 cases (rural-urban migrant households).
The Chinese Household Income Project collected data in 1988, 1995, 2002, and 2007. ICPSR holds data from the first three collections, and information about these can be found on the series description page. Data collected in 2007 are available through the China Institute for Income Distribution.

本项目旨在测算并估算中华人民共和国城乡地区的个人收入分布及相关经济因素。项目首席研究员以现金报酬及多类额外收入构成项为基础，界定了收入的定义。数据采集工作于2002年末通过在城乡地区开展的多轮问卷访谈完成。

本项目包含10个独立数据集。前4个数据集源自城市问卷调研：数据集1收录城镇常住居民个体数据；数据集2收录城镇家庭数据；数据集3收录从初始城市访谈表单中提取的个体层面经济变量；数据集4收录从初始城市访谈表单中提取的家庭层面经济变量。第5个数据集为村级层面数据，通过访谈村级管理人员获取。第6个数据集收录农村常住居民个体数据。第7个数据集收录农村家庭数据，以及面向农村家庭开展的社交网络问卷的大部分数据。第8个数据集收录社交网络问卷的剩余数据，且专门针对农村学龄儿童的活动情况。第9个数据集收录从农村迁移至城市的移民个体数据。第10个数据集收录城乡移民家庭数据。

数据集1包含151个变量，共20632个观测样本（城镇常住居民个体）。数据集2包含88个变量，共6835个观测样本（城镇家庭）。数据集3包含44个变量，共27818个观测样本，其中至少6835条为空观测样本，用于在数据文件中分隔家庭单元，数据集3的其余有效观测样本与数据集1的样本一一对应。数据集4包含212个变量，共6835个观测样本，与数据集2的样本一一对应。数据集5包含259个变量，共961个观测样本（行政村）。数据集6包含84个变量，共37969个观测样本（农村常住居民个体）。数据集7包含449个变量，共9200个观测样本（农村家庭）。数据集8包含38个变量，共8121个观测样本（农村学龄儿童个体）。数据集9包含76个变量，共5327个观测样本（城乡移民个体）。数据集10包含129个变量，共2000个观测样本（城乡移民家庭）。

中国家庭收入项目（Chinese Household Income Project, CHIP）分别于1988年、1995年、2002年及2007年开展数据收集工作。校际政治与社会研究联合会（Inter-university Consortium for Political and Social Research, ICPSR）收藏了前三次调研的数据，相关信息可在该系列数据集的描述页面查询。2007年采集的数据可通过中国收入分配研究院获取。
