Source metadata Source metadataMost countries that provided census or register data have applied a random rounding procedure intended to prevent the disclosure of individual information. This procedure consists in randomly rounding each data cell to the closest upper or lower multiple of 3 or 5. Any figure extracted from the database reflects this procedure and the population totals or subtotals may therefore vary slightly from one table to the other. In order to improve the reliability of the population estimates from the labour force surveys, several surveys over the period 1998-2002 have been stacked and the figures have been averaged over this period. The significance thresholds provided by Eurostat for individual surveys were adapted to reflect the increased sample size resulting from this operation, taking into account the overlap between two successive surveys. No cell with a population below these calculated thresholds can be published, and the cells are assumed to have a zero population.
Data source(s) used Data source(s) usedThe sources for this database are mainly census data, from the 2000 round of censuses. Census data were used for 22 countries. Countries not taking periodic censuses but keeping population registers have provided data extracted from these registers; this is the case for four countries: Denmark, Finland, Norway and Sweden. For some countries, not all themes covered in the database are present in the national census or register. Labour force surveys, provided by Eurostat and averaged over the period 1998-2002, have been used to fill the gaps where possible.
Population & Scope Population & Scope Other coverage Other coverageSector
Sectors of activity are recorded according to the International Standard Industrial Classification Rev. 3 (ISIC, cf. UN, 1989), at the division level (two-digit level, 60 sectors). Some countries have only been able to provide data at the tabulation category level (one-letter level, 17 sectors).
Countries do not necessarily record activities in censuses or registers according to ISIC and may use national classifications instead. Most national classifications are close enough to ISIC to allow a correct mapping at the two-digit level, but this is not always the case. When the internal logic of the national classification is too distant from that of ISIC, the mapping is at best imperfect.
For some countries, the final classification in the database is at the one-letter level. For a number of others, in order to preserve the available information, the classification is a mix between the one-letter level and the two-digit level.
The list of sectors in ISIC (one-letter level) is reproduced in Table A.7. For practical reasons, the first two tabulation categories of ISIC (A: Agriculture, hunting and forestry, and B: Fishing) have been aggregated in the database to form a top-level sector labelled A_B.
Statistical population Statistical populationThis database contains information on several demographic and labour market characteristics of the population of 28 OECD countries around the year 2000, by country of birth. The OECD countries included are Australia, Austria, Belgium, Canada, the Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Japan, Luxembourg, Mexico, Netherlands, New Zealand, Norway, Poland, Portugal, the Slovak Republic, Spain, Sweden, Switzerland, Turkey, the United Kingdom and the United States.
Most of the thematic files of the database include three core variables: the country of residence, the country of birth and educational attainment. Other variables available in the database include age, gender, citizenship, duration of stay, labour force status, occupation, sector of activity and field of study.
In general, the database covers only employed persons aged 15 and older.
