9. MICS4 Survey Design Workshop What to save? DevInfo databases Wallcharts Factsheets Press releases And lots more!!

10. MICS4 Survey Design Workshop When When to archive? Archiving is often seen as the last step in data collection activities As a result, documentation is often of uneven or poor quality Start archiving when you start the survey and prepare electronic copies of all the documents you produce

11. MICS4 Survey Design Workshop How How to archive datasets? Save datasets –in original format (e.g. CSPro files) –in analysis file format (e.g. SPSS *.sav file) Always include descriptions with data –Label all data within each file Variable labels Value labels

12. MICS4 Survey Design Workshop How How to archive documents? Save as much as possible electronically –Paper documentation disappears –Electronic documentation has a longer life Save documents –in original format –in HTML –as PDF files Record information not already in key documents Use an archiving tool –International Household Survey Network Microdata Management Toolkit
