Panel and cohort studies:

Panel Study of Income Dynamics
PSID is a nationally representative longitudinal study of nearly 8,000 US families. Following the same families and individuals since 1968, the PSID collects data on economic, health, and social behaviour.

The German Socio-Economic Panel Study
The SOEP is a wide-ranging representative longitudinal study of private households. It provides information on all household members, consisting of Germans living in the Old and New German States, Foreigners, and recent Immigrants to Germany. The Panel was started in 1984. In 2003, there were more than 12,000 households, and nearly 24,000 persons sampled.

Canadian Survey of Labour and Income Dynamics
The SLID is an important source for income data for Canadian families, households and individuals. Introduced in 1993, SLID provides an added dimension to traditional surveys on labour market activity and income: the changes experienced by individuals and families through time. At the heart of the survey's objectives is the understanding of the economic well-being of Canadians.SLID also provides information on a broad selection of human capital variables, labour force experiences and demographic characteristics such as education, family relationships and household composition. Its breadth of content, combined with a relatively large sample, makes it a unique and valuable dataset. (pdf introduction to SLID).

The Cross-National Equivalent File
Cross-National Equivalent File (1980-present) contains a selection of equivalently defined variables from six national houshold panel surveys: the Panel Study of Income Dynamics (PSID), the German Socio-Economic Panel (GSOEP), the British Household Panel Study (BHPS), the Canadian Survey of Labour and Income Dynamics (SLID), and the Household Income and Labour Dynamics in Australia (HILDA), and the Swiss Household Panel (SHP). The time period covered by these different panels varies. The data are designed to allow cross-national researchers not experienced in panel data analysis to access a simplified version of these panels, while providing experienced panel data users with guidelines for formulating equivalent variables across countries. Most importantly, the equivalent file provides a set of constructed variables (for example pre- and post-government income and United States and international household equivalence weights) that are not directly available on the original surveys. Variables from the Cross-National Equivalent File can be easily merged with the data from the original surveys.

National Longitudinal Study
US Department of Labour longitudinal surveys:

National Youth Survey (University of Colorado)
The National Youth Survey began in 1976. At that time 1,725 adolescents between the ages of 11 and 17 years old as well as one of their parents were interviewed. Participants were chosen by a scientific method designed to select individuals representative of the national population. 28 years later this study is ongoing and has been commended by policymakers, scholars and researchers as one of the most influential studies of the present time. Now called the National Youth Survey - Family Study (participants who were once 11-17 are now 39-45) this study has followed these individuals throughout time to look at their changing attitudes, beliefs and behaviors about topics such as career goals, involvement with community and family, attitudes about violence, drugs, and social values.


Repeated cross-sections:

Below we highlight a few notable internationally harmonised repeated cross-sectional surveys. There are a great many other relevant studies of this nature (for other listings, see UKDA - ESDS International; ICPSR series list; EDACwowe).


Luxembourg Income Study

The LIS database is a collection of household income surveys. These surveys provide demographic, income and expenditure information on three different levels: household, person and child.


IPUMS (census harmonisation project)

IPUMS is a project dedicated to collecting and distributing census data from the USA and from around the world. Its goals are to:

IPUMS-international currently (2008) supports access to micro-data from 35 countries, covering 111 different censuses and 260 million person records, spanning the time period 1960-2005.

IPUMS-USA currently supports access to census micro-data from the USA from 1850 to 2000.



PISA, a three-yearly survey (2000, 2003, 2006...) of 15-year-olds in the principal industrialised countries. It assesses how far students near the end of compulsory education have acquired some of the knowledge and skills that are essential for full participation in society.

European Social Survey

The European Social Survey is a biennial survey (2001, 2003, etc) focussing on attitudes and lifestyles in European countries. The ESS has proved a popular and influential source of attitudinal data for international comparative research in the last decade.
