Our Data

LIS collects and harmonises socio-economic micro datasets from upper- and middle-income countries and makes them available into

Luxembourg Income Study Database (LIS) the largest available harmonised income micro-database
Luxembourg Wealth Study Database (LWS) the first cross-national wealth database in existence

Make data accessible to researchers world-wide

Microdata that would otherwise be incomparable, or impossible to access, are made available to researchers world-wide through:

LISSY A remote system for registered researchers and exclusively for non-commercial purposes
Web Tabulator An online table maker to design and generate cross-national descriptive tables
Key Figures National indicators on Inequality and Poverty based on LIS Microdata

Cross-national comparative research

LIS Databases have been used by thousands of researchers coming from diverse disciplines, primarily economics, sociology, political science and the policy sciences to conduct cross-national comparative research on socio-economic outcomes. Over the last 30 years, many researchers use the LIS data to analyse variation in socio-economic outcomes within and across countries. Making the LWS data available has also enabled entirely new lines of research about wealth, debt and other dimensions of economic well-being.

Research based on LIS microdata has appeared in dissertations, journal articles, and books, informs NGOs and policy-makers, and is often featured in the popular media. All research based on LIS and LWS microdata is catalogued in our Working Paper series.

Combination of our microdata with country-level data from other sources is possible to study the relationship between LIS-generated indicators and other outcomes such as family wellbeing, political behaviour, and macroeconomic conditions. Visit our Other Databases page.
