Chinese Household Income Project, 1995 (ICPSR 3012)
The purpose of this project was to measure and estimate the distribution of personal income 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: payments in kind valued at market prices, agricultural output produced for self-consumption valued at market prices, the value of food and other direct subsidies, and the imputed value of housing services. The rural component of this collection consists of two data files, one in which the individual is the unit of analysis (Part 1) and a second in which the household is the unit of analysis (Part 2). Individual rural respondents reported on their employment status, level of education, Communist Party membership, type of employer (e.g., public, private, or foreign), type of economic sector in which they were employed, occupation, whether they held a second job, retirement status, monthly pension, monthly wage, and other sources of income. Demographic variables include relationship to householder, gender, age, and student status. Rural households reported extensively on the character of the household and residence. Information was elicited on type of terrain surrounding the house, geographic position, type of house, and availability of electricity. Also reported were sources of household income (e.g., farming, industry, government, rents, and interest), taxes paid, value of farm, total amount and type of cultivated land, financial assets and debts, quantity and value of various crops, amount of grain purchased or provided by a collective, use of chemical fertilizers, gasoline, and oil, quantity and value of agricultural machinery, and all household expenditures (e.g., food, fuel, medicine, education, transportation, and electricity). The urban component of this collection also consists of two data files, one in which the individual is the unit of analysis (Part 3) and a second in which the household is the unit of analysis (Part 4). Individual urban respondents reported on their economic status within the household, Communist Party membership, sex, age, nature of employment, and relationship to the household head. Information was collected on all types and sources of income from each member of the household whether working, nonworking, or retired, all revenue received by owners of private or individual enterprises, and all in-kind payments (e.g., food, durable goods, and nondurable goods). Urban households reported total income (including salaries, interest on savings and bonds, dividends, rent, leases, alimony, gifts, and boarding fees), all types and values of food subsidies received, and total debt. Information was also gathered on household accommodations and living conditions, including number of rooms, total living area in square meters, availability and cost of running water, sanitary facilities, heating and air-conditioning equipment, kitchen availability, location of residence, ownership of home, and availability of electricity and telephone. Households reported on all their expenditures including amounts spent on food items such as wheat, rice, edible oils, pork, beef and mutton, poultry, fish and seafood, sugar, and vegetables by means of coupons in state-owned stores and at free market prices. Information was also collected on rents paid by the households, fuel available, type of transportation used, and availability and use of medical and child care.
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.

Panel Study of Income Dynamics (PSID): Main Interview, 1968-2015 (ICPSR 37142)
This catalog record includes detailed variable-level descriptions, enabling data discovery and comparison. The data are not archived at ICPSR. Users should consult the data owners (via PSID) directly for details on obtaining the data.
The PSID is the world's longest-running nationally representative household panel survey. With over 50 years of data on the same families and their descendants, the PSID is a cornerstone of the data infrastructure for empirically based social science research in the U.S. PSID gathers data on the family as a whole and on individuals residing within the family, emphasizing the dynamic and interactive aspects of family economics, demography, and health. PSID data were collected annually from 1968-1997 and biennially after 1997. In the Main Interview, one person per family is interviewed on a regular basis. Information about each family member is collected, but much greater detail is obtained about the reference person and, if married/cohabitating, the spouse or long-term cohabitor. Survey content changes to reflect evolving scientific and policy priorities, although many content areas have been consistently measured since 1968. Information includes employment, income, wealth, expenditures, health, education, marriage, childbearing, philanthropy, and numerous other topics. With low attrition and high success in following young adults as they form their own families, the sample size has grown from roughly 5,000 families in 1968 to more than 10,000 families and 24,000 individuals by 2017. Over the course of the study, the PSID has distributed data on more than 80,000 individuals. The long panel, genealogical design, and broad content of the data offer unique opportunities to conduct generational and life-course research. The PSID now contains thousands of inter- and intragenerational relationships over 50 years of data, including:
- "Paired" generational relationships, with each family in the pair providing independent interviews (as of the 2017 wave)
- Parent-Adult Child pairs: ~5,500
- Sibling pairs: ~3,600
- Cousin pairs: ~4,500
- "Tripled" generational relationships, with all three generations providing independent interviews (as of the 2017 wave)
- Grandparent-Parent-Adult Child triplets: ~1,400

Survey content changes to reflect evolving scientific and policy priorities, although many content areas have been consistently measured since 1968. Information includes employment, income, wealth, expenditures, time use, health, dementia screener, insurance, education, marriage, childbearing, philanthropy, and numerous other topics. Additional types of PSID data are available only under a restricted contract. These include but are not limited to: geospatial data below the level of state; mortality data; Medicare claims; and educational characteristics from the National Center for Education Statistics.
With low attrition and high success in following young adults as they form their own families, the sample size has grown from roughly 5,000 families in 1968 to more than 9,000 families and 24,000 individuals by 2021. Over the course of the study, the PSID has distributed data on more than 84,000 individuals. The long panel, genealogical design, and broad content of the data offer unique opportunities to conduct generational and life-course research.
The PSID now contains thousands of inter- and intragenerational relationships over 50 years of data, including (as of the 2021 wave):
- "Paired" generational relationships, with each family in the pair providing independent interviews
- Parent-Adult Child pairs: ~4,300
- Sibling pairs: ~5,200
- Cousin pairs: ~5,400
- "Tripled" generational relationships, with all three generations providing independent interviews
- Grandparent-Parent-Adult Child triplets: ~1,000
