  1. Internet data collection in the LFS Danish experiences Paris, April 2010

  2. Outline • Background • Preparations • The pilot • Going full-scale • Quality? • Further work

  3. Background 1 • The Danish LFS has individuals as sampling unit • Until 2010 household variables collected via proxy in final interview • From Q1 2010 Denmark collects household variables as required by regulation no. 577/98

  4. Background 2 • Grant given from Eurostat in 2008 • Initial work on differences between CATI- and CAWI-interviews

  5. Preparations • Discussions on collection modes: • How much CATI? • How many reminders? • Letter vs. phone reminders? • Two parallel universes

  6. The Pilot • Two reference weeks as sample • Two weeks interview period • Two groups: Aldi vs. Irma • Aldi: baseline with no reminders • Irma: Two phone reminders and optional CATI

  7. Pilot – the results • What was learned: • Reminder needed • 2nd reminder not necessary • CATI option needed • Showed that a pilot was essential

  8. Going full-scale • Not a big problem • Not possible to keep as separate universes – today one big survey.

  9. Preliminary results Q1 2010

  10. Quality • Accepted a possibly lower quality. • Primary issues: NACE, ISCO • Further study needed • Setup test vs. quality test

  11. Further work • In-depth quality analysis • Coding of NACE and ISCO • Analysing the mode effects of CAWI in core-LFS

  12. Thank you! Paris, February 2010 Sammy Lauritsen ssl@dst.dk
