Linking CPC to Other Classifications: UN Statistics Division

This presentation explores the possible links between CPC and other classifications such as HS, SITC, COICOP, and EBOPS, highlighting the challenges and opportunities in establishing these connections. The focus is on product-based classifications and their applicability in different statistical contexts.

Presentation Transcript

  1. Linking CPC to other classifications United Nations Statistics Division

  2. What links are possible? • CPC is used for statistics based on products • Any classification that uses a product concept or can establish a link to a product concept can be linked to CPC • This makes a CPC-COFOG link easier than an ISIC-COFOG link • In this presentation we will consider the most common applications: • HS, SITC, COICOP, EBOPS • ISIC link was covered earlier

  3. CPC Ver.2 – HS 2007

  4. CPC – HS link • CPC provides basic definitions (building blocks) for services • For goods, the HS provides these building blocks, i.e. each CPC goods subclass is the sum of HS subheadings • Problem: HS is tailored for international trade and does not reflect all locally produced products in a suitable fashion

  5. CPC – HS link • Examples: • 1. Sugar cane – grouped with Locust beans; fruit stones and kernels and other vegetable products (including unroasted chicory roots of the varietyCichorium intybus sativum) of a kind used primarily for human consumption, not elsewhere specified or included.

  6. CPC – HS link • Examples: • 2. Software – included in Discs, tapes, solid-state non-volatile storage devices, "smart cards" and other media for the recording of sound or of other phenomena, whether or not recorded, including matrices and masters for the production of discs, but excluding products of Chapter 37.

  7. CPC – HS link • Examples: • 3. HS often groups raw and processed agricultural products (which are outputs of different industries) • 4. HS agricultural products often do not distinguish source by animals (e.g. cow milk, vs. goat milk etc.) • Unlike for services, HS adds a constraint to possible CPC detail

  8. CPC – HS link • CPC provides detail beyond HS in a few selected areas • Total: 268 products (of 1501) = 17.8% • Out of which 195 for agriculture/food products • (Many splits will be reflected in the next HS revision) • Other main areas: • Books • Petroleum oils • Software • Toys • Computer equipment

  9. CPC-HS link • Since most CPC subclasses are defined through HS subheadings, the explanatory notes of the HS provide the basis for defining the content of these CPC subclasses • For subclasses that involve splits of HS subheadings, separate explanatory notes have been provided • Note: some text in the HS explanatory notes is not applicable to all CPC uses • E.g. software packaged with a computer

  10. CPC – HS link (and more) • In general, CPC has changed with the underlying HS categories • For services, CPC provides the detail and other classifications, like EBOPS, use these building blocks

  11. CPC Ver.2 – SITC Rev.4 CPC Ver.2 – BEC

  12. CPC-SITC, BEC • Since SITC and BEC are derived from HS, the link between CPC and these classifications is simply based on the established CPC-HS link with the appropriate aggregations • Different aggregation structure results sometimes in split links between CPC and SITC or BEC • Use of simplified links?

  13. CPC – COICOP, COFOG etc. • Classifications of expenditure according to purpose (COFOG, COICOP, COPNI, COPP) • Unit of classification is the transaction • Transactions can be linked to products (goods or services provided) • Therefore a “natural” link exists between these classifications and the CPC

  14. CPC – COICOP, COFOG etc. • Problem: • COICOP etc. define and group transactions by purpose • The grouping criteria and individual boundaries may not be compatible with CPC, which is production-based • The scope of the four classifications differs and is only a subset of the CPC scope • Example for COICOP scope problems: • Food products can be used at home or further processed by other industries • Cars can be used by households or by businesses • Therefore many links could be considered partial (depending on application)

  15. CPC – EBOPS • EBOPS (Extended Balance of Payments Services Classification) is the main classification used for Statistics of International Trade in Services • EBOPS classifies services and can therefore be linked to the CPC • EBOPS is an extension of the services part of the BOP classification • Original version of Manual on Statistics of International Trade in Services included a link between CPC 1.1 and EBOPS (and GNS/W/120)

  16. CPC – EBOPS • Since EBOPS operates at higher aggregation than CPC, EBOPS categories are typically aggregations of CPC subclasses • This makes EBOPS a classification derived from CPC • Due to broad definition of EBOPS categories, the EBOPS-CPC link also serves as detailed definition for many categories • EBOPS 2010 has 120 categories (excluding supplementary items) • In the correspondence shown, the additional link to GNS/W/120 requires additional splits and makes the link look more complicated than necessary

  17. CPC – EBOPS Problem: • CPC groups services according to their characteristics • EBOPS does the same, but makes exceptions, where services are grouped by provider type or mode of supply • Travel • Services between related enterprises

  18. CPC – EBOPS • The Manual is currently under revision • Review process completed this summer/fall • Final expected early 2010 • CPC-EBOPS correspondence is not yet available • Will not include a GNS link in the same table • Will eliminate some of the exceptions • CPC will serve as definition for the EBOPS categories

  19. Alternate aggregations for CPC

  20. Alternate aggregations for CPC • Similar to alternate aggregations for ISIC, it may be useful to group products in ways different from the default CPC structure for specific purposes

  21. Alternate aggregations • No such aggregations existed in previous CPC versions • Although there was an alternate structure for financial products • CPC Ver.2 introduces an alternate aggregation for products of the Information Economy

  22. Products of the Information Economy • This aggregation defines ICT products and Content and media products in terms of CPC subclasses • This is a complement to the definition of the Information Economy (ICT sector and Content and media sector) in ISIC Rev.4

  23. ICT products [Link] • There are 99 ICT products, grouped into 10 broad level categories • Computers and peripheral equipment • Communication equipment • Consumer electronic equipment • Miscellaneous ICT components and goods • Manufacturing services for ICT equipment • Business and productivity software and licensing services • Information technology consultancy and services • Telecommunications services • Leasing or rental services for ICT equipment • Other ICT services

  24. Content and media products [Link] • There are 74 Content and media products, grouped into 6 broad level categories • Printed and other text-based content on physical media, and related services • Motion picture, video, television and radio content, and related services • Music content and related services • Games software • On-line content and related services • Other content and related services
