Data Archiving—What is It? • Data Archiving refers to the long-term storage of data and its affiliated documentation. • In addition to storing the census or survey data, we’ll store its metadata—descriptive information about the census or survey data; essentially, “data about other data”. • Today’s storage medium is no longer file cabinets and storage rooms, but the Internet and portable storage mediums such as CDs. MICS4 Data Processing Workshop
Why Document Data? • Facilitates the understanding and usage of data—without this documentation, your data will not be understood and hence, will not be properly used and/or analyzed • Reduces staff time needed to assist data users • Allows for reuse of materials for future efforts (training guidelines, field manuals, advertising campaigns, etc) • Can use the data to determine a framework for future survey needs MICS4 Data Processing Workshop
Archiving Benefits to Users • Maximizes access to data—data is available 24/7 • If properly documented, decreases time a user spends understanding your data • Increases efficiency for researchers—less time is spent producing pre-determined tables, more time can be devoted to higher-level analysis • Reduces duplication of effort—if only users can find your data MICS4 Data Processing Workshop
Archiving Benefits to Agency • Increased visibility and credibility for the Agency • Increases the quality of research from your data • Improves reliability and relevance of your data through feedback • Allows for easier management of the data and its resources • Is a valuable and irreplaceable asset that should be managed in a way that encourages their widest possible use and re-use MICS4 Data Processing Workshop
Data Expectations of Users • Dataset free of errors—no spurious or out-of-range values, simple consistency checks performed, record counts match...no surprises! • Dataset easy to use, well-documented • Have information available to fully understand the survey, especially: • Sample design, selection, and weighting • Field procedures • Data processing procedures (include programs if possible) • Any editing that occurred (in the field and/or office) • The dataset(s) themselves! MICS4 Data Processing Workshop
MICS Documents to Save • Questionnaires • Interviewer & field manuals • Sample selection, listing information • Excel files, other supporting documents • Explanations of any event(s) that impacted the sample selection, survey dates, etc • Reports, planning materials, budgets, staff organization • Any other documentation you think will be helpful to understanding your survey MICS4 Survey Design Workshop
MICS Datasets to Save • SPSS Files: • Household (HH) • Household listing (HL) • Insecticide-Treated Nets (TN, optional) • Women (WM) • Birth History (BH, optional) • FGM (FG, optional) • Children age 0-4 years (CH) • Men (MN, optional) • CSPro Files: • Final (merged, not individual clusters) HH data file • GPS data (optional) MICS4 Data Processing Workshop
MICS Programmes to Save Software Programmes & Files: • CSPro dictionaries • CSPro data entry & menu systems • CSPro secondary editing & menu systems • CSPro GPS Entry program • CSPro export & SPSS recode • SPSS tabulation programmes • Any country-specific programmes MICS4 Data Processing Workshop
MICS Dissemination Materials to Save • Wall charts • Factsheets • Press releases • And lots more! MICS4 Data Processing Workshop
When to Archive? • Archiving is often the last step in data collection activities • As a result, documentation is often of uneven or poor quality Start archiving when you start your MICS survey MICS4 Data Processing Workshop
How to Archive Documents? • Save as much as possible electronically • Electronic documentation has a longer life and is more readily usable • Paper documentation requires permanent storage areas • Paper documentation disappears! • Save documents • in original format • in HTML • as PDF files • Record information not already given in key documents • Use an archiving tool—we’ll discuss the International Household Survey Network’s (IHSN) Microdata Management Toolkit MICS4 Data Processing Workshop
How to Archive Datasets? • Save datasets • in original format (e.g., CSPro raw+final files) • in analysis file format (e.g., SPSS.sav file) • Always include descriptions with data—provide labels within each file for: • Variable labels (e.g., “Result of Interview”) • Value labels (e.g., 1=Complete, 2=Not at home) • Don’t forget to document country-specific questions! MICS4 Data Processing Workshop
International Household Survey Network (IHSN) • Established September 2004 as a recommendation of the Marrakech Action Plan for Statistics (MAPS) • Users: International organizations actively sponsoring household surveys + local NSOs • Governing committee members from DFID, ILO, Paris 21/OECD, UNICEF, UNSD, WHO, World Bank • Distributes Microdata Management Toolkit and NADA • Find out more at http://www.ihsn.org/toolkit MICS4 Data Processing Workshop
IHSN Components • Archive creation: Metadata Editor • Document your survey data, documentation, and metadata in accordance with international metadata standards (DDI and Dublin Core). • Dissemination: CD-ROM Builder • Facilitates the publication of survey data, documentation, and metadata onto CD-ROMs and the Internet using HTML format • Nesstar Explorer • Using their free program, access metadata and data, and export to common statistical formats • IHSN Report Center • Provides diagnostics on your metadata, dataset relations, external resources, etc., and creates a PDF of your study documentation (a summary report of all your documentation) MICS4 Data Processing Workshop
What is the Metadata Editor? Template-driven specialized editor Import/Export common data files Integrated interface, multi-lingual support Metadata and data in single file MICS4 Data Processing Workshop
What is the CD-ROM Builder? Publishes survey metadata, data, and documents on a CD-ROM or website Stores archive in an HTML-based language Users can customize the layout (branding) and content of the CD (single or multi-surveys) Integrates with IHSN’sMetadata Editor MICS4 Data Processing Workshop
Installation • Unzip IHSN_Toolkit_v1.1_full.zip into C:\MICS4\IHSN • Double-click on the file “IHSN Toolkit Installer.exe” • Select the first option,Metadata Editor MICS4 Data Processing Workshop
