1. Situation of OECD annual national accounts database

Joint OECD-Eurostat questionnaire for the transmission of data

Availability of data (see table pages 3-4)– Improvements in completeness, timeliness and coverage for

tables 0101-0112.– Significant weakness: tables 1400 and 2000.

Dissemination of data (paper, CD-ROM and OLISnet)– Volume 1 Main aggregates - in January, free access on

Internet for all users.– Volume 2 Detailed tables - in July – the electronic version

covers, in addition, detailed non-financial accounts by sectors. Free access to officials via OLISnet, in OECD.STAT

1. Situation of OECD annual national accounts database (ctd)

– Volume 4 General Government Accounts - in December –. Free access to officials via OLISnet, in OECD.STAT

Situation of the metadata transmission to the OECD– General government metadata– Employment metadata

Methodological changes– Different methodologies processed separately– Linkages of main aggregates– Example : Luxembourg GDP at current prices

2. New features of the joint OECD-Eurostat questionnaire

Reorganisation – several of the tables 0101-0112 are merged. Suppression and reduction

– Tables 0113-0116, 0118, 0122-0127, 0119, 1400 are dropped– Table 0800: transactions and sector detail are reduced.

Extensions– Table 0301-0303: A60 breakdown (ISIC Rev.3 division)– Table 0302: GFCF in construction– Table 0303: additional employment breakdown by sector– Table 0501: full COICOP 3-digits for households– Table 1100: split between 1101 for GG and 1102 for sub sectors– Table 2000 and 2200: new cross-classification A17 (A60) x AN_F6

Recommendations

Special effort should be made to supply tables on fixed assets.

Data should be transmitted on the day the data are released by Member country sna.contact@oecd.org

European Member countries are asked to send the questionnaire to both OECD and Eurostat at the same time.

sna.contact@oecd.org

3. The COFOG2 Project

A reminder : extension of table 1100: Strong demand in the European context for more

disaggregated government expenditure data to improve the analysis of trends in the composition of government expenditure

Eurostat and the OECD agreed on extending table 1100 to the 2nd level of COFOG only for the level of general Government (S.13).

The OECD proposed to extend the project to non-EU countries

8

The COFOG2 Project for non-EU countries

A questionnaire was sent to 8 non-EU countries last December. None of them seems able to transmit COFOG2 data in a near future.

Only Australia and the United States publish data which resemble the COFOG2 classification

9

The COFOG II Project for EU countries

Up to now 15 countries transmitted data to Eurostat on the second level of COFOG

Many problems of classification still need to be solved.

Creation of an electronic discussion group and preparation of a manual on sources and methods for COFOG statistics compilation

10

The COFOG2 Project

In 2006 OECD had to postpone the issue of the new Table 1101.

New meeting of the EU Task Force on COFOG scheduled next February. Hopefully preliminary data on COFOG2 will soon be made public.

The OECD is engaged in many studies on public expenditure efficiency which would really benefit from more disaggregated public expenditure data.

Rationale:Rationale: Capitalise on StandardsCapitalise on Standards

National Account standards exist already: SNA93 defines a standard for national account statistical data. NSOs submit data files in a standard coding and format.

Data Dissemination standards exist already: XML is the world standard for transmitting data between

applications and organizations. SDMX-ML is the XML standard for defining, transmitting,

validating, and interpreting statistical data and metadata between organisations.

NAWWE capitalises on these standards to: Enhance national accounts data collection at the OECD. Provide other international organisations access to the same

data collection standards. Facilitate data sharing and dissemination processes for NSOs.

NAWWE 2006:NAWWE 2006: StatusStatus

XML Schemas and Structure Files: Data and Metadata structure definitions have been created

based on SDMX-ML V 2.0 XML schemas. Concepts included in the Metadata structure definition

have been drawn from a draft version of the SDMX cross domain metadata concepts.

Objectives of the Web Application: http://stats.oecd.org/nawwe/ Generic loading of dimensions by interrogating data structure

definition within structural XML.

Ability to transform selected data or whole data files into alternative formats (GESMES, Excel, CSV).

Tools to validate the quality of data and metadata (e.g. quantification of revision changes, missing information).
