ContentsContents
• Comparison of national practices for three OECD MSs and three broad issues: - Canada, Korea and UK; - in terms of index as a whole, variables used to measure service production activities and their deflators.
• Conclusions and questions

Index: compilationIndex: compilation
ISP should measure net output or the value added of various service sectors
• Canada: monthly value added from deflated SA gross output
- output indicators are benchmarked to the output values of deflated I/O tables.
• Korea and UK: in general, use gross output directly - changes in gross output are frequently used as
approximate indicators of change in net output: - deflated turnover weighted by those compiled from VA of
service sectors.

Index: typesIndex: types
• Canada publishes indices for more than 50 groups.
• UK also publishes indices at division levels in five aggregated groups in addition to one for total: - Distribution, Hotel and restaurants, Transport and communications, Business services and finance, Government and other services.
• Korea publishes indices for total service and for: - non-financial services and indices for each Category; - as well as indices for knowledge based service, etc.

Index: timelinessIndex: timeliness
The overall index is available:• Canada and UK: about 2 months after the end
of the reference month;
• Korea: about 40 days after the end of the reference month.

Index: coverageIndex: coverage (main issues)(main issues)
• Due to the inclusion of a wide range of activities in the services sector, it is hard to compare: - differences of coverage across sectors; - differences of coverage within a sector.
• Differences in coverage due to: - interests of each country; - statistical environment; - user needs; - etc.
![Page 10: Review of country practice on Index of Service Production](https://reader036.fdocuments.us/reader036/viewer/2022082712/56813b5d550346895da455e9/html5/thumbnails/10.jpg)
Variables: sourcesVariables: sources• Canada: more than 30 sources, but 4 main surveys: - Survey of Employment, Payrolls and Hours; Monthly Survey
of Manufacturing; Retail Trade Survey; Wholesale Trade Survey.
• Korea: 2 main surveys and a few other sources: - Current Service Industry Survey; Current Wholesale and
Retail Trade Survey; and Data from other organisations (such as financial, insurance and health institutions).
• UK: a number of surveys and administrative information, e.g.:
- Monthly Inquiry into the Distribution and Service Sector; Retail Sales Inquiry; Expenditure and Food Survey; etc.

Variables: typesVariables: types
• 2 types: volume and/or (deflated) value
• Korea: use no volume data but value only: - Gross turnover and gross operating revenues
for all activities.
• Canada and UK: use of both volume and deflated value data.

Deflators: comparisonDeflators: comparison
• Korea uses the simplest deflation system with PPI and CPI; - no combined deflators are used.
• Canada and UK use a wide range of deflators, which cover consumer, producer, trade, overall economy as well as combined deflators. - UK deflating system is the most complex.
• No common practices across the 3 countries except for ‘Hotel and Restaurant’ (H) and ‘Recreational, cultural and sporting activities’ (92).

Conclusions and questions Conclusions and questions (for (for STESEG)STESEG)
Similarities• Types of sources• Coverage across sectors• Timeliness & frequency
Significant differences• Compilation methodology• Coverage within sectors• Types of variable used• Types of deflator used• Title of the index
Question: whether STISTF should attempt to harmonise the differences?
- If it should, then to what extent?
