For U.S. and NC Statistics - The Triangle Census Research Data Center (TCRDC) is a partnership between the U.S. Census Bureau and Duke University in cooperation with the University of North Carolina System. Under this partnership, the Census Bureau provides access to unpublished microdata from the Bureau's economic and demographic censuses and surveys via a secure computer laboratory located on the Duke Campus. Faculty, students, and staff from Duke or any of the 16 universities in the UNC System may use the TCRDC free of cost for their Census approved research projects, making the TCRDC is a unique opportunity for researchers in the region.
