  1. Implementing the economic classification revision (NACE / ISIC) in the Business Register by Fabio Tomasini Head of the Business Register Unit 05.07.07

  2. Summary • Development of NACE Rev. 2 national (Swiss) version • Implementation in the Business Register • Implementation in the Statistics

  3. Context: supporting documentation • Eurostat created three handbooks providing a set of tools to be used during the process of implementation of NACE Rev. 2: • http://circa.europa.eu/irc/dsis/nacecpacon/info/data/en/index.htm • Setting up an implementation plan • Implementation in Business Registers • Sampling and Estimation

  4. Context: activity code as a general reference • Reference in statistics • Reference outside statistics: insurance companies, banks, etc. use it to organise their fields of activity • Activity code used as general reference: marketable value in Switzerland

  5. 1. Elaborating the Swiss national version of NACE Rev. 2 • National consultations (national and regional government, professional associations, partners, clients), first, on NACE Rev. 2 structure, then, on national 6th digit • Discussions and analysis: according to which criteria should a further specification at the level of the 6th digit be granted or refused? Number of enterprises, employment, turnover, information available…

  6. Timetable for implementing NACE Rev. 2 in Switzerland

  7. Documentation of the Swiss national version of NACE Rev. 2 • Publications available to users: • Theoretical introduction • Explanatory notes • Headings / structure • Weighted conversion matrix (correspondence table) • Documentation on changes • Coding assistance tool (online software) • http://www.bfs.admin.ch/bfs/portal/fr/index/infothek/nomenklaturen/blank/blank/noga0/revision_noga_2007.html

  8. 2. Implementation in the Business Register • Automatic recoding of all units having a 1: 1 relation between NACE Rev. 1.1 and NACE Rev. 2 • Manual recoding of all units having a 1: n or n: m relation based on survey questionnaires filled in by active enterprises during 2005 Enterprise Census (no additional survey conducted) development of a weighted conversion matrix based on the manual recoding (for each unit there is a NACE Rev. 1.1 code and a NACE Rev. 2 code)

  9. NOGA 2008 Recoding Assistance Tool for the Enterprise Census 2005 units

  10. 2. Implementation in the Business Register • Automatic recoding of all deleted, fictitious or inactive units found in the 1: n or n: m NACE Rev. 2 relation groups, based on weighted conversion matrix • Specific quality controls for units in this category

  11. 2. Implementation in the Business Register • Business register’s switch: June 14 2007 • Double-coding during a few years to allow NACE Rev.2 implementation in all statistics as well as time series calculations • For collaborators and partners: specific training, coding handbook (practical auxiliary rules), coding assistance tool

  12. NOGA 2008 : Double coding

  13. NOGA 2008 : Double coding NOGA-Code 2008 : 331100

  14. NOGA 2008 : Double coding

  15. NOGA 2008 : Double coding

  16. 3. Implementation in the statistics • Approximately 30 statistics (structural business statistics, short term statistics, synthesis statistics) are involved. Coordination must be assured to guarantee a coherent system (NACE Rev. 2 implementation will be carried out from 2008 until 2011, coordinated with the National Accounts) • Plan time needed to recalculate survey plans • Evaluate back-casting strategies and their costs • Develop global publication plan (data will be published according to two different classifications)

  17. Conclusion • Classification changes do make a difference • (an entirely different structure) • Communication and coordination: important assets before and during the project • After the project: analyse impact on statistics results (dissemination of changes) and explain it to users
