The Luxembourg Income Study (LIS) is a cross-national data archive located in Luxembourg. The LIS archive contains two primary databases.  The LIS Database includes income microdata from a large number of countries at multiple points in time. The newer LWS Database includes wealth microdata from a smaller selection of countries. Both databases include labour market and demographic data as well. Registered users may access the microdata for social scientific research using a remote-access system. All visitors to the website may download the LIS Key Figures, which provide country-level poverty and inequality indicators.
