ihsn: progress and plans

The Accelerated Data Program ( ADP )The International Household Survey

Network ( IHSN )

PARIS21 Steering CommitteeParis, 5 November 2008

IHSN: progress and plansProgress• Further development of our microdata management tools

– Microdata Management Toolkit– NATIONAL DATA ARCHIVE application– Microdata anonymization tools (initiated)– + documentation and dissemination guidelines (preservation of digital materials)

• Development of the IHSN Question Bank• Maintenance of the IHSN survey catalog• WFP new IHSN member• IHSN evaluated as part of MAPS Plans for next months• Microdata anonymization tools and guidelines• Question Bank• Survey quality assessment framework

ADP: progress and plansProgress• Demand for ADP Task 1 is still growing. • ADP Task 2 (harmonization and improvement of survey methods

and programs) is being implemented in Cameroon, Mali and Nigeria.

• ADP Task 3 (support to data collection) is limited.• ADP evaluated as part of MAPS Plans for next months• Expand Task 1• Continue piloting Task 2 in 5-6 countries• Continue (limited) Task 3

• Documenting helps harmonizing• Documenting helps identifying data gaps• ADP Task 2: assessing and improving

quality of survey data• Mid term proposed solution: international /

national question banks (XML repository of re-usable survey metadata)

Improving survey quality and data harmonization

ADP implementation: pilot Countries

Africa• Burkina Faso, Cameroon, Ethiopia, The Gambia, Ghana, Guinea *, Kenya, Liberia, Mali,

Mauritania *, Mozambique, Niger, Nigeria, Senegal, Tanzania, Tunisia, Uganda (+ Botswana, Lesotho, Namibia and Swaziland [TFSCB])

Asia• Bangladesh, Fiji, Indonesia, Lao PDR, Mongolia, Philippines, Sri Lanka, Thailand, Vietnam

Central and South America• Argentina, Bolivia, Costa Rica, Dominica, Guatemala, Haiti*, Honduras, Mexico, Peru,

Uruguay

Middle East• Yemen*

Looking Forward: Tools and guidelines for 2009

• Microdata Management Toolkit: Building on success• Dissemination Policy Guidelines: • Anonymization tools: Preserving Confidentiality• Comprehensive protocol in metadata preservation • Guidelines on improving:

o Data Processingo Data Analysiso Data Qualityo Survey Methodology

• Release of the Survey Quality Assessment Framework• Release of a beta version of the Question Bank

Application

Microdata Management Toolkit• Software + guidelines + training materials• For data documentation: DDI Metadata Editor

• Access policies and procedures are crucial to protect data

• IHSN “Policy Guidelines & Recommendations”:– Why / how / when / to whom

should microdata be disseminated?

– Practical guidelines with suggested access agreement forms, etc.

• To be adapted to country specificities

Dissemination Policy Guidelines

Microdata Management Toolkit

CDROM and Web-Builder Web cataloguing system

• For data dissemination: open-source tools

Anonymization Tools• By a Task Force; building on existing

work• Not an integrated software.• Using power of statistical packages

for processing complex algorithms• A collection of specialized tools for:– Measuring the risk– Reducing the risk– Assessing the information loss • Intelligent system– To generate anonymized subsets on-

demand

National Data Archives

Over 125 survey metadata in DDI available in NAData Archive in 2008

• Guidelines on improving:oData ProcessingoData AnalysisoData Qualityo Survey Methodology

• Protocols for the long-term preservation of statistical data and metadatao Not only survey microdata but: administrative data, census

maps, master samples, registers and time series data

Guidelines & Best Practics

• Survey Quality Assessment Frameworko Survey Manager’s guidelines and checklist for

process control from: budgeting to archivingo Assuring quality through process

standardization

• Question Bank Application: Mark McConaghy
