What It Is

The TRDC is part of a network of Federal Statistical Research Data Centers across the country that provide secure access to restricted-use Federal microdata for approved research projects.  Begun by the Census Bureau, a Census employee continues to facilitate access at each site although a variety of statistical agencies now supply datasets through this network.

Here's an introductory video from the Census Bureau.

The TRDC has long been supported by Triangle institutions including UNC, Duke, and RTI International.  Duke maintains another site of the TRDC on its west campus.

What Data Are Available?

See the list of available data. These data sets are not otherwise publicly available.  Application procedures vary depending on the sponsoring agency. 

Agencies contributing data include:

  • the Census Bureau
  • the Agency for Healthcare Research and Quality
  • the Bureau of Economic Analysis
  • the Bureau of Labor Statistics
  • the National Center for Health Statistics, and
  • the National Center for Science and Engineering Statistics

Hosting data in the RDCs requires a Memorandum of Understanding between the Census Bureau (which runs the centers) and any other agency so this list changes. Check the site linked above frequently.
