Issues in Design and Estimation
Robert ManchinGallup Organisation, Europe
Citizens and Governance in a Knowledge-Based Society
First Call in Area 6
Brussels, 11th November 2004
Outline
• Background •Consortium Partners:
–UNODC, Max Planck Institute, UNICRI, CEPS
•Objectives of EU-ICS Survey– Sample Allocation– Data Collection Design
• Issues
– Estimation • Issues
• Access / Data Lab, Future Applications
What if?
• Landline coverage is not the same in the 25 countries? (coverage error 1)
• Mobile only is not a high status, but low status attribute – and status and victimization related?
• Mix of nophone / land only / mobile & landline /mobile only is changing ?
Objectives
• Objective 1: Estimate personal and household crime (VICTIM / SAFETY) rates at the National and EU level
• Objective 2: Estimate personal and household crime rates at the NUTS2 level
Data Collection Design
• Phone Data Collection with centralized RDD sample management
• n = 2000/per country with capital city boosted samples
Telephone Data Collection and Design
Landline Only Landline
& Mobile Mobile Only
Non-telephone Households
Estimation
•Single Frame
•Dual Frame– Landline– Mobile
•Multiple Frame– Landline– Mobile– Non-telephone
Nuts 2 Estimates a.k.a. Small Area Estimation
• Margin of error – Nuts 2 – 2.4% to 9.9%
• Capital cities small area estimation
– Synthetic– Past data– Borrow strength
Issues of access, collaboration
• EU funding requirements– 50% of costs only– One-time research budget / original R&D, no
strict repetition– Sustainable, on-going monitoring /
benchmarking with corresponding “business model”
– Consortium of users? Subscription based?
Capital city – combination of survey data with process-produced data
