1. Proposed IPUMS-International Secure Data Enclave Patricia Kelly Hall pkelly@umn.ed

2. Ribbon Cutting Ceremony, Oct 27, 2010: Inauguration of MPC-USCB Research Data Center Pres. Bruininks (U Minnesota) & Director Graves (USCB)

3. National Stats Office Questionnaire Data collection Data processing Aggregate statistics Tabulator Public samples Full microdata Samples drawn Public samples IPUMS samples Harmonization Aggregate statistics IPUMS Sampling Donation Confidentiality Individual-level analysis

4. IPUMS-International Integrated MicrodataSamples 1 to 11 % samples Loss of geographic detail Top-coding of values Suppression of sensitive variables and values Grouping of small case count values Suitable for many research projects Secure Data Enclave 25 % samples to full count Additional geographic detail Access to full array of values Access to sensitive variables and values Identification of un-grouped values Necessary for some research projects

5. Data Security Model Valid statistical purpose Trusted researchers Anonymisation of data Technical controls around the data Disclosure control of results → safe project → safe people → safe data → safe setting → safe data output ------------------------ ⁼ safe use of data

15. IPUMS-International Features of the Proposed Secure Data Enclave Secure facilities similar to USCB Research Data Enclave Application approval processes similar to RDCs Different levels of user access to specific data Countries will benefit from more detailed analysis of the demographic and economic processes Secure sites at MPC, National Statistical Office, and/or national universities/research institutes

16. Proposed Calendar Secure Data Enclave Project 2011: NSO’s endorse project 2012: MPC pilots integrated full-count microdata for selected countries 2013: SDEs replicated within countries and extended to other countries 2014: Certified Virtual Secure Data Enclaves extended to National Statistical Office, and/or national universities/ research institutes
