Data Archiving

MICS4 Survey Design Workshop

Data archiving refers to the long-term storage of data and documentation

Survey and census microdata are valuable resources for government departments and academic researchers

They constitute valuable and irreplaceable assets which should be managed in a way that encourages their widest possible use and re-use.

Data archiving

MICS4 Survey Design Workshop

Why archive data?

• Collecting data is expensive • Data can and should be used beyond

producing basic report• Examples:

– Able to examine trends examine trends if you have a series of datasets over time

– Allows in-depth analysis in-depth analysis of important subject areas

MICS4 Survey Design Workshop

• Difficult to find any information without documentation

• Difficult to perform analyses and to interpret findings

• Data are useless without documentation

• Allows reuse of documents for future surveys

Why document data?

MICS4 Survey Design Workshop

What do users expect?• Well documented data• Comprehensive• Clear, consistent, easy to use data• Information to be able to

– Fully understand the survey, especially• Sample design, selection and weighting• Field procedures• Data processing• Datasets

– Accurately analyze and use data

WhenWhen 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

HowHow 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

MICS4 Survey Design Workshop

HowHow 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

MICS4 Survey Design Workshop

Microdata Management ToolkitTools to facilitate archive and dissemination of surveys

• International Household Survey Network [IHSN]• Established in September 2004• International organizations actively sponsoring household surveys + NSOs• Coordination: ILO, DFID, Paris 21, UNICEF, UNSD, WHO, World Bank• http://www.surveynetwork.org
