Head of the Business Register Unit

Summary l.jpg
Summary

  • Development of NACE Rev. 2 national (Swiss) version

  • Implementation in the Business Register

  • Implementation in the Statistics


Context supporting documentation l.jpg
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


Context activity code as a general reference l.jpg
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


1 elaborating the swiss national version of nace rev 2 l.jpg
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…



Documentation of the swiss national version of nace rev 2 l.jpg
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)

2 implementation in the business register l.jpg
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)

2. Implementation in the Business Register Census 2005 units

  • 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

2. Implementation in the Business Register Census 2005 units

  • 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

3 implementation in the statistics l.jpg
3. Implementation in the statistics Census 2005 units

  • 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)


Conclusion l.jpg
Conclusion Census 2005 units

  • 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
