The California Census Research Data Centers
(CCRDCs) at UCLA and UC Berkeley are two of nine Research Data Centers
(RDCs) established by the Center for Economic Studies (CES) of the U.S.
Bureau of the Census in order to provide secure physical locations for
researchers to study non-public microdata collected by the Census Bureau.
These microdata files contain data that cannot be released publicly
because they contain detailed information on geographic location and/or
other characteristics about the firms or households that could disclose
All proposals for research to be conducted at the CCRDC must undergo a
rigorous and lengthy review process. Proposals are reviewed for feasibility,
scientific merit, benefit to the Census Bureau, and disclosure risks.
Before beginning any research at the CCRDC, a researcher must have an
approved project and have received Special Sworn Status (SSS) from the
Census Bureau to begin work in the restricted-access laboratory. All work
must be done on-site in the secure CCRDC lab facility. All research
output to be removed from the CCRDC is subject to stringent disclosure
analysis to prevent release of any confidential information.
Research proposals may be submitted throughout the year at the Center
for Economic Studies website at www.ces.census.gov.
Researchers contemplating submitting proposals in any of the review
cycles should expect a minimum of four to six months to elapse between
proposal submission and the start of research, and possibly longer if
Federal Tax Information is requested. Researchers should contact the
appropriate CCRDC administrator (UCLA or UCB) to discuss the proposal
submission process. Preliminary proposals should be submitted to the
CCRDC administrator for consideration at least one month prior to the
deadline for receipt of full proposals.
The CCRDC does not offer any research services,
nor does it provide assistance to individuals or organizations seeking
statistics or public-use datasets. For such services, please visit the
Census Bureau website at www.census.gov,
or the Demographic Research Unit of the California Department of Finance
