The Luxembourg Income Study Center at the Graduate Center (LIS Center) is a research, development, and administrative satellite of LIS.

The LIS Center serves as the link between the Graduate Center community and the parent institute, LIS, located in Luxembourg. LIS and the LIS Center are both directed by Janet Gornick, professor of political science and sociology at the Graduate Center of the City University of New York.
 
LIS, formerly known as the Luxembourg Income Study, is a non-profit microdata archive and research institute. LIS, located in Luxembourg since 1983, serves a global community of researchers, educators and policy makers. LIS acquires datasets with income, wealth, employment, and demographic data from a large number of countries, harmonises them to enable cross-national comparisons, and makes them available for public use by providing registered users with remote access. The LIS archive includes two primary databases, the Luxembourg Income Study Database, which focuses on income data, and the newer, smaller Luxembourg Wealth Study Database, which focuses on wealth data.
