9. 59th Conference of European Statisticians (CES), 14 June 2011, Geneva 59th Conference of European Statistics (CES), 14 June 2011, Geneva 8 The 2011 Data Collection Strategy: Retrieving and returning 3 steps: 1. Re-use of available dataData sharing & data warehousing 2. Use of new registers and other secondary sources Traditional government-based registers Information from private businesses Data on the internet (web-crawlers) 3.Primary data collection: 1.EDI technologies, like XBRL 2.Web surveys 3.traditional modes: paper, CATI, CAPI Using new social media technologies Reciprocity: report back to respondents Multi-source designs Mixed-mode designs
