LIS, formerly known as Luxembourg Income Study, is a data archive and research center dedicated to cross-national comparative micro data analysis. LIS acquires datasets with income, wealth, employment, and demographic data from many high- and middle-income countries, harmonises them to enable cross-national comparisons, and makes them publicly available in two databases, the Luxembourg Income Study Database (LIS) and the Luxembourg Wealth Study Database (LWS). LIS is an internationally respected venue for cross-national research in the social sciences, serving as a host of international conferences, visiting scholars, and pre-and postdocs and a virtual host for scholarly exchange. The LIS office, located in Esch-Belval (Luxembourg) and directed by Professor Daniele Checchi, houses a team of professionals who perform the essential roles of the organisation: data acquisition, harmonisation; documentation; technical and user support; instruction; and core administration. Many of the staff conduct research using the LIS and LWS microdata. The US LIS Satellite Office contained within the Stone Center on Socio-Economic Inequality located at The Graduate Center of The City University of New York (US), is overseen by Janet Gornick, Professor of Political Science and Sociology at CUNY. The US LIS Satellite Office plays a key role in providing support and liaison services to the team in Luxembourg.
