The Luxembourg Income Study, asbl (LIS) is a non-profit project 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. In 2006 the database included data from 30 countries on four continents, 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 subscribe and pay an annual fee which supports the project.
