What is ISIC?







International Standard Industrial Classification of All
Economic Activities (ISIC)
The official activity classification of SNA
To classify economic entities (units) according to
activity they carry out
Original ISIC 1948
Rev 1 1958, Rev 2 1968, Rev 3 1989
Minor Revision 3.1 2002,
Major Revision 4 planned for 2007

Design principles & priorities for ISIC rev 4

Improve international comparability

Relevance

–
–
–
–


convergence of regional classifications
E.g. NAICS,NACE,JSIC,CSIC,ANZSIC etc
engage more countries & regions in ISIC design
target for international comparability at least 2 digit level
Information sector, internet , telecoms
OECD ICT definition
environmental services
new technologies
growing business service sector
health services
tourism
agriculture
Continuity – long time series
Level of detail for an international classification?

ISIC rev 4: A Top-top Structure?
What are SNA needs?



SNA AEG, OECD and Eurostat national accountants
have agreed need for top-top structure to ISIC rev 4
of about 10 categories
OECD national accountants proposed that
intermediate aggregation of 30-40 categories useful
for international comparison within OECD. SNA AEG
in Dec 2004 were undecided.
Currently OECD and Eurostat use A6/A17/A31/A60
aggregations of ISIC rev 3 in national accounts
questionnaires

Proposed set of ISIC 4
SNA data aggregations?




A*10/11 top-top
A*21 = ISIC rev 4 Sections
A*38 = ISIC rev 4 Sections + 17 sub-sections
(intermediate)
A*88 = ISIC two digit divisions

OECD exercise

Autumn 2004 set aim to agree top-top and intermediate ISIC 4
aggregations for reporting national accounts data by activity

Initial proposals from Eurostat, UNSD and France

OECD analysts raised issues:
–
international comparability, relevance, and continuity for long time
series analysis;
–
the needs of input-output, policy interests, productivity analysis,
separately identifying activities that follow different tracks in economic
cycle

OECD SNA Industry EDG established to encourage participation

Proposals developed in consultation with Eurostat and UNSD

Process


First OECD proposal circulated February 2005
Revised proposal in light of comments 24 May
– Set out specific questions on most contentious issues



Sent to all OECD member national accountants,
EDG, classifications experts, Eurostat, UNSD
Reviewed by UNSD Expert Group on Classifications
June 2005
Comments received from 15 countries, Eurostat and
ECB

Constraints

Preference for following ISIC structure

ISIC 4 draft was changed in March and August 2005
– now finalised

Some ISIC structural and ordering changes on real
estate and public administration made for top-top

Take into account current ISIC 3 aggregations

Consider Eurostat A65 draft & US BEA GDP by
industry (~65)

Issues for intermediate aggregation



Comparable SNA data reporting for Europe, N
America and Asia-pacific and preferably wider
Follow ISIC order and hierarchy
Consider analytical relevance and continuity

ICT, R&D, Energy, Distributive trade
Keep approximate A31 level of detail for
manufacturing – for continuity and robustness of data
More service activities

Eurostat and US A65 levels

comparability
– Yes 11, No 3

Agree split on human health and social work
– Yes 12, No 3

Break out R&D
– Yes 13, No 3

Break out manufacturing at about same level as A31


Keep the group manufacture of transport equipment as in A31
– Yes 9, No 4

Questions and Proposed Next Steps

Can these proposed aggregations be accepted for SNA data
reporting? In particular:

Do you agree the A*10/11 proposals are suitable for an ISIC
top-top aggregation for SNA data reporting

Do you agree the proposed intermediate A*38 is suitable for
SNA data reporting?

Any further comments are invited

Subject to delegates views a final OECD paper would be
submitted to ISWGNA in November for consideration by the
SNA AEG January 2006

P.S.: Should a standard grouping for service activities be
recommended or not?
