CCRDC California Census Research Data Center Berkeley The CCRDC is a joint project of the U.S. Bureau of the Census and the University of California Berkeley (and UCLA) to enable qualified researchers with approved projects to access confidential, unpublished Census Bureau data CCRDC on the web:

Purpose of Census Research Data Centers Access to non-public use dataAccess to non-public use data Secure facilitySecure facility Presence of Census Bureau employeePresence of Census Bureau employee Benefits to Census BureauBenefits to Census Bureau –Necessary for access to Title 13 and Title 26 data –Not required for NCHS, AHRQ data if not linked to Title 13 data

Why do we need RDCs? (Why is access to microdata restricted?) Perceptions of improper use could – Reduce response rates – Induce Congress to cut funding/programs Title 13 U.S.C protects confidentiality – Identifying microdata cannot be released – Only Census Employees/temporary staff can look at individually identifiable data – Access must provide legitimate benefits to Census Bureau programs

Why use CCRDC data? Not available elsewhereNot available elsewhere –Establishment level business data –Linked household-firm (LEHD) data More detail than anywhere elseMore detail than anywhere else –Detailed geo-spatial variables –Virtually no top or bottom coding –Possible to link to other non-Census data High Quality Sampling FramesHigh Quality Sampling Frames ExtensibilityExtensibility

Access and Disclosure Issues All researchers must be Census Bureau employees or have Special Sworn StatusAll researchers must be Census Bureau employees or have Special Sworn Status –Fingerprints, security forms, penalties Projects must showProjects must show –Benefits to Bureau –Scientific Merit –Feasibility –Need for non-Public use Data –Minimal Risk of Disclosure All output goes through disclosure review process (Interim and Final Outputs)All output goes through disclosure review process (Interim and Final Outputs) –Statistical output: Yes –Tabular Output: No
