The National Center for Charitable Statistics (NCCS) is the national repository of data on the nonprofit sector in the United States. Its mission is to develop and disseminate high quality data on nonprofit organizations and their activities for use in research on the relationships between the nonprofit sector, government, the commercial sector, and the broader civil society.

Working closely with the IRS and other government agencies, private sector service organizations, and the scholarly community, NCCS builds compatible national, state, and regional databases and develops uniform standards for reporting on the activities of charitable organizations.

The Center was established in 1982 and has been a project of the Center on Nonprofits and Philanthropy (CNP) at the Urban Institute since July 1996, when it was transferred from the research division of INDEPENDENT SECTOR.
