LIS Cross-National Data Center, formerly known as the Luxembourg Income Study (LIS), is a non-profit organization registered in Luxembourg which produces a cross-national database of micro-economic income data for social science research. The project started in 1983 and is headquartered in Luxembourg. The database includes over 300 datasets from about 50 high- and middle-income countries, with some countries represented for over 30 years. Nationally representative household income survey data is commonly, though not exclusively, provided by the participant country's national statistics collection agency (e.g. Statistics Canada; the Australian Bureau of Statistics). These and other agencies make annual financial contributions which support the database production and maintenance.
