This presentation discusses the challenges and strategies in producing Public Use Microdata Files (PUMFs) for surveys at Statistics Canada. Key highlights include the necessity of evaluating survey costs, adjustments in PUMF content, and limited software tools. The presentation also emphasizes the commitment to producing legacy survey files dating back to October 1998, while seeking additional financial support for continued PUMF creation and documentation. Effective communication with the Data Liberation Initiative (DLI) is essential for addressing priorities and gathering feedback on produced files.

PUMF Creation • Not all surveys require a PUMF • Sometimes costly to produce • Survey teams disbanded • Outputs are scrutinized by the Microdata Release Committee
PUMF Alternatives • Include PUMF in cost-recovery contracts • Reduced PUMF content • No PUMF
Use of SPSS • SPSS not widely used at Statistics Canada • Statistics Canada has signed a corporate license with SAS • SPSS cards may have to be generated by someone else
Remote Job Submissions • Remote job submissions handled only as part of initial survey contracts • $80 per request • No plans in place to expand service in Special Surveys Division
Production of Legacy Survey Files • Committed to producing survey files back to October 1998 • Pre-October 1998 files may be generated (on a fee for service basis)
Dissemination Budget • DLI provides some financial support each year • Additional funds are required to continue PUMF creation, documentation and support of legacy files
DLI Requirements/Feedback • Need to know your priorities • Continued communication with DLI • Require feedback on files produced
