The Chinese Household Income Project (CHIP) has conducted five waves of household surveys, in 1989, 1996, 2003, 2008 and 2013. They covered the income and expenditure information in 1988, 1995, 2002, 2007 and 2013 respectively and called CHIP1988, CHIP1995, CHIP2002, CHIP2007, and CHIP2013. These surveys were carried out as part of a collaborative research project on incomes and inequality in China organized by Chinese and international researchers, with assistance from the National Bureau of Statistics (NBS). The CHIP project participants and other researchers have analyzed the data from these four waves and published a wide range of articles, reports, and books.
All the CHIP waves contain surveys of urban and rural households. In view of the increased importance of rural-to-urban migration, and because the urban and rural household subsamples do not adequately cover migrants, the 2002 survey added a survey of rural-to-urban migrants. Thus, the 2002 CHIP survey includes three subsamples. The same procedure was adopted for the 2007 survey, which is also composed of three parts: the urban household survey, the rural household survey, and the rural-to-urban migrant household survey.
