The System of National Accounts (SNA) 2008 is the international statistical standard

for the measurement of economic developments, such as GDP & Government debt

ESA 2010 is the corresponding European version of the SNA 2008

The Statistical standard includes both conceptual issues such as definitions of

sectors, instruments, classifications valuations and reporting templates (called

“transmission programs”) including timetables for transmitting the statistics

The story of the System of National Accounts

The International reporting templates (called “transmission programs”) provide

the methodological specifications associated with each statistical series – selected

from the statistical standard.

It is the statistical description associated with each series, which (i) makes each

series statistical accurate and provides consistent (ii) clarity for each reporting agent

The reporting templates are drafted by methodological experts from

international organisations.

This could be (i) from a smaller; (ii) same (iii) or larger group of IOs, who

participated to and govern the International Statistical Standard

Reporting templates specify the statistical specifications associated with each series

It specifies the methods associated with each series, such as

Adjustments methods - if the series is seasonal and/or working day adjusted

Valuation methods - if the series is valuated as nominal or market value

Maturity type - if the series is reported as original or residual maturity

Prices - if the series is recorded in current or constant prices

Unit measurement - if the unit is measured in USD and in millions

Exchange rate methods - if the end-of-month exchange rate is applied

The detailed reporting templates are then converted into unique code classifications

domains specifying the relevant dimensions, code lists with descriptions

This is a conversion of the detailed statistical methodology specified in the reporting

templates into uniquely identifiable codes for each statistical series

This conversion makes it feasible to instruct computers to identify the statistics and

to transmit this to other computers, where the statistics can then be stored, checked,

processed or published automatically, in a fast, reliable and on a frequent basis

SDMX is the statistical standard which facilitates and reduces manual, labour intense

and prone to error work, freeing up qualified resources

The SDMX codes are drafted jointly by methodological experts together with IT

experts and stored for public access within a SDMX Global Registry

This conversion could be done by a (i) smaller; (ii) same; or (iii) larger group of IOs,

who participated in drafting the international reporting templates

Local publishing of the statistics

Enabling the quality checks, dissemination, presentation and release of

the international statistics to users and the general public

By releasing the (i) statistics, (ii) SDMX codes and (iii) metadata any

user can extract local statistics automatically

Enhances the usability, availability and synchronisation of releasing

statistics among international organisations

The “Inter-Agency Group” (IAG) was formed to coordinate the publishing

of macroeconomic statistics among IOs and to assure that that releases of

new macroeconomic statistics are synchronised across all international

organisations

The (IAG) consists of BIS, ECB, EUROSTAT IMF, OECD, UN and WB

CCSA members may reflect and discuss the following four considerations

Possible CCSA working method

Can today’s presentations be applied to the work of CCSA

and for strengthening the cooperation among its members?

2. These teams could coordinate and

- identify variations in methodology among the international reporting templates

- discuss the methodological choices with the aim of converging towards common

methodology

CCSA members may reflect and discuss the following considerations

1. CCSA members with interest in the same statistical standards may benefit

from coordinating the international reporting templates and SDMX schema

Possible CCSA working method

CCSA members may reflect and discuss the following considerations

4. These teams could coordinate

- draft work plans and timetables within own work programmes

- the implementation of the SDMX codes within own statistical production

- the synchronisation of releases among international organisations

3. These teams could coordinate the SDMX standards by

- developing the SDMX domain and the associated SDMX code lists
