Local access to to non-public microdata from the Census and several other federal surveys can be accessed by submitting a proposal to the Triangle Census Research Data Center (TCRDC), housed at Duke University and supported in partnership with the UNC system. The review process involves two stages, a preliminary proposal and a final one. Final proposals are reviewed for feasibility, scientific merit, benefit to the Census Bureau, and disclosure risks. Benefit to the Census Bureau must be a predominant purpose.
Be forewarned, the Census Bureau indicates researchers should expect a minimum of three months to elapse between the final proposal submission and the actual commencement of research. This duration can vary greatly depending on the specifics of the proposal. However, approved researchers affiliated with Duke or any UNC system campus are granted access free of charge while others must pay for the privilege. See the TCRDC web site (linked above) for detailed information on this program, including proposal guidelines, and contact TCRDC staff directly with questions.
