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.
Data Characteristics Data Characteristics Other data characteristics Other data characteristicsEducation Level: The International Standard Classification of Education (ISCED; cf. UNESCO 1997) was used as a baseline, but groups have been aggregated as follows:
•Primary level: ISCED 0/1/2.
•Secondary level: ISCED 3/4.
•Tertiary level 1: ISCED 5A/5B.
•Tertiary level 2: ISCED 6.
Some countries were not able to provide data distinguishing between Tertiary 1 and Tertiary 2: this was the case for Austria, France, the United Kingdom, Hungary and Japan. Whenever labour force surveys had to be used, because of the limited sample size, levels ISCED 5 and ISCED 6 were aggregated into a single tertiary education category.
A more compact classification with three levels (Primary, Secondary and Tertiary) has therefore been produced to reflect the lowest common denominator.
Population & Scope Population & Scope Other coverage Other coverageKey statistical concept: Age is recorded in 5-year age groups when the source is a census or a register (generally 15-19, 20-24, etc. to 65-69 and 70+). When the source is a labour force survey, because of limited sample size, only three broad age categories are recorded in the database: 15-24, 25-64 and 65+. This broader classification was also extended to the other countries for the purposes of comparability.
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 all individuals aged 15 and older.
