The Organisation for Economic Cooperation and Development (OECD) is an international organisation established in 1961 to stimulate economic progress and world trade. It originates from the Organisation for European Economic Cooperation (OEEC), founded in 1948 to coordinate the Marshall Plan for the reconstruction of Europe after second world war (Salzman 2000: 774-775). As of 2009, the OECD grouped 30 member countries, and had active relationship with some 70 other countries.

One of the main purposes of the organisation is to achieve the highest possible economic growth and employment and a rising standard of living in the member countries. As the OECD lacks the power to enforce its recommendations, it is essentially an advisory body. In part for this reason, the organisation is a major producer of statistics and macroeconomic analyses, covering economic and social issues from macroeconomics to trade, education and development. In many of these fields, the OECD has become an authoritative source of statistical data (Salzaman 2000: 778).


The OECD maintains several databases, covering a wide range of topics. Data can be accessed through four different portals on OECD’s website: Statistics Portal, OECD.Stat, SourceOECD and OECD Index of Statistical Variables (links provided in each of the separate reviews ). The four portals contain many of the same variables, but the interface, functionalities and download options vary. The portals are therefore examined separately. Most of the data are also published in printed publications, such as OECD Factbook, OECD in Figures and OECD Economic Outlook.

Data types and sources

The OECD publishes a variety of statistical data, mainly from official registers, administrative records, national accounts and censuses. Some statistics are also based on surveys and research programmes, such as labour force surveys and the Programme for International Student Assessment (PISA).

OECD Index of Statistical Variables


The OECD Index of Statistical Variables is an alphabetical listing of frequently requested variables that link to predefined tables containing those variables, and to the databases or publications on SourceOECD in which the listed variables may be found. The listing contains 142 variables and covers a broad range of topics such as demography, economy and finance, education, the labour market, and social expenditure.

Geographical coverage

Most of the datasets in the Statistics Portal cover the 30 member countries of the OECD, 23 of which are European. Some datasets also cover non-member countries, such as Brazil, China and Russia. The OECD also publishes some regional statistics.

Time coverage and updates

The time coverage varies: many of the key economic indicators are available from about 1960, while other indicators, such as obesity and reading test scores, are published only for more recent years.The dataset with the longest time scope is the Historical Statistics for the World Economy (Maddison 2001), which for some countries contains data from the year 1 AD. Some of the key economic indicators, such as GDP figures and unemployment rates, are updated several times a year, others annually. Some series are discontinued.


The documentation provided in the predefined tables varies, but is generally rather limited. In many cases, users must consult the original publications to get a detailed understanding of the variables.

Comparability and data quality

The OECD (2003: 2) prides itself of producing, in some areas, statistics that “are internationally recognised as the ‘best’ in terms of coverage, timeliness, and comparability.” Furthermore, the improvement of the data quality is seen as a key objective at the OECD and was one of the main aims of the OECD Statistics Strategy (OSS) launched in 2001 (ibid: 5). Nonetheless, even though data are presented as comparable in standardised tables, some problems of comparability are likely to remain. The progress of the OSS can be traced at the OECD Statistical Programme of Work website (link provided below).
