From April 2003 National Accounts data are entirely consistent with OECD Quaterly National Accounts.

In order to facilitate cross country comparisons, seasonally adjusted volume indices are now available for OECD Member countries (except for Czech Republic, Greece, Hungary, Iceland, Ireland, Luxemburg, Poland, Slovak Republic and Turkey) for:

Gross Domestic Product
Private final consumption expenditure
Governement final consumption expenditure
Gross fixed capital formation
Exports of goods and services
Imports of goods and services

Zone estimates are calculated using country data converted from national currencies by the 1995 GDP Purchasing Power Parity (PPP).

Series are quarterly with the exception of Greece and Luxemburg who do not currently produce quarterly national accounts.

Gross Domestic Product and Expenditure on GDP are also available at market prices in national currency.
Quarterly data are at quarterly levels except for Canada, Mexico, the United States and Japan who publish quarterly national accounts data at annual levels.

A list of all suppressed and all new series can be found in the attached csv file (NEWSERIES_QNA.CSV and SUPPSERIES_QNA.CSV).

Series identifier for Quarterly national Accounts are built in the following way:

Country code.Series code.Measure code

The country code is the ISO country code.

Series codes and titles are standardised whenever the data are comparable.
See below the standard set of titles and corresponding codes.
However, when a series is substantially different from the standardised title,
the difference is indicated both in the title and in the series code.

Series Code Series Title

GDP BY TYPE OF EXPENDITURE

EXPGDP Gross domestic product
EXPPC Private final consumption expenditure
EXPGC Government final consumption
EXPGF Gross fixed capital formation
EXPST Increase in stocks
EXPEXP Exports of goods and services
EXPIMP Imports of goods and services
EXPSD Residual item


COMPARATIVE VOLUME INDICES

CMPGDP Gross domestic product
CMPPC Private final consumption expenditure
CMPGC Government final consumption
CMPGF Gross fixed capital formation
CMPEXP Exports of goods and services
CMPIMP Imports of goods and services


Measure code
The measure code is made of the information contained in the three following elements.

* First element : valuation

C Current prices
VNB Constant prices, national base year
LNB Chained constant prices, national base year
VOB Constant prices, official OECD base year (1995)
DNB Implicit price deflator, national base year = 100
DOB Implicit price deflator expressed with 1995 = 100
VIXNB Volume index, national base year = 100
VIXOB Volume index expressed with 1995 = 100
CPC Current prices converted with current PPPs
VPC Current prices converted with 1995 PPPs
VPVOB Constant 1995 prices converted with 1995 PPPs

* Second element : level of the quarterly data

AR The quarterly data for a series are expressed at annual level
QR The quarterly data for a series are expressed at quarterly level

* Third element : seasonal adjustment

SA The quarterly series is seasonally adjusted

LEADING INDICATORS

The lists of turning points used in the calculation of the CLIs have been updated in December 2002, with the exception of Italy, Spain (turning points for these two countries were updated in 2001), Mexico, Greece, Luxembourg and Switzerland. As a result, the level of the CLI data has been modified. At the same time, some component series have been dropped or replaced, to improve the overall timeliness of the CLIs. In addition, a CLI for Turkey has been included.
More information can be found at http://www.oecd.org/std/cli .

A list of the new components series and a list of the suppressed components series can be found in the attached csv file (NEWSERIES_SUPPSERIES_CLI.CSV).

DATA AVAILABILITY FOR NON-MEMBER COUNTRIES

From January 2003, only data for the six major Non-Member countries (Brazil, China P.R., India, Indonesia, Russia and South Africa) are included and published in the MEI publication and related electronic version. However, all other Non-Member countries previously included in MEI are from January 2003 only available (free) on the OECD web-site (www.oecd.org) in a document entitled "Main Economic Indicators: Non-Member Countries". This document can be located by selecting directorates, statistics and statistics for Non-Member countries.

EURO TREATMENT

From February 2002, the national currencies of the 12 Euro Member countries are expressed in euro. All historical data (i.e. pre 2001 for Greece and pre 1999 for all other euro area countries) are calculated by applying the fixed irrevocable exchange rates. However, pre European Monetary Union euro are notional units and are not always suitable to form area aggregates. For further details see the article by Schreyer and Suyker in the February 2002 edition, Statistics Brief Number 2, published by the Statistics Directorate of OECD.

Note that, for all Euro area countries, data for periods after accession (i.e. 1999 onwards, 2001 onwards for Greece) are expressed in true euro.

SEASONAL ADJUSTMENTS

New seasonal adjustments by OECD are generally carried out once a year,when the December figure is available. Revisions to individual series
due to new seasonal adjustments by national source or by OECD are not signalled in this note.
