The foreign-born population covers all people who have ever migrated from their country of birth to their current country of residence. The foreign-born population data shown here include people born abroad as nationals of their current country of residence. The difference across countries between the size of the foreign-born population and that of the foreign population depends on the rules governing the acquisition of citizenship in each country. This indicator is measured as a percentage of population.

The difference across countries between the size of the foreign-born population and that of the foreign population depends on the rules governing the acquisition of citizenship in each country. This indicator is measured as a percentage of population.

The native-born employment rate is calculated as the share of employed native-born persons aged 15-64 in the total native-born population (active and inactive persons) of that same age. Employed people are those who worked at least one hour or who had a job but were absent from work during the reference week. This indicator is measured in percentage of native-born population of the same age by gender.

The foreign-born employment rate is calculated as the share of employed foreign-born persons aged 15-64 in the total foreign-born population (active and inactive persons) of that same age. Employed people are those who worked at least one hour or who had a job but were absent from work during the reference week. This indicator is measured in percentage of foreign-born population of the same age by gender.

The native-born unemployment rate is calculated as the share of unemployed native-born persons aged 15-64 in the native-born labour force (the sum of employed and unemployed native-born) of that same age. Unemployed persons consist of those who report that they are without work during the reference week, are available for work and have taken active steps to find work during the four weeks preceding the interview. Immigrant workers are affected to a greater extent by unemployment than native-born workers in European countries that have traditionally received migrants. This indicator is measured as a percentage of native-born labour force.

The native-born participation rate is calculated as the share of employed and unemployed native-born persons aged 15-64 in the total native-born population (active and inactive persons) of that same age.

This indicator presents the stock of foreign-born population in OECD countries, that is, the size of immigrant populations as measured in number of persons. Data on immigrant populations may be collected through registers, residence permits, statistical surveys, or censuses, depending on the country.
