Population by migration status

In international discussions on immigration and integration, the term population with a migration background is used with growing frequency. This concept is increasingly used to replace the simple distinction between citizens (or nationals) and foreign citizens (or non-nationals), which does not take into account whether individuals are themselves immigrants or have an indirect connection to migration through their parents' migration experiences.

The "population with a migration background" as defined by the FSO includes all foreign nationals, naturalized Swiss citizens, except for those born in Switzerland and whose parents were both born in Switzerland, as well as Swiss citizens at birth whose parents were both born abroad.

Typology of the population by migration status

Following similar approaches in many other countries, the FSO has drawn up a typology of the population by migration status for Switzerland on the basis of UN international recommendations.

A person's migration status is defined by combining the following variables: the "country of birth", the "nationality (current and at birth)" of the reference person, as well as the variables "country of birth" of both parents.

In 2019, about 38% of the permanent resident population has a migration background (2,722,000). More than a third of this population (992,000) has Swiss nationality. Four-fifths of the persons with a migration background belong to the first generation (2,202,000). The remaining fifth was born in Switzerland and is thus part of the second generation (520,000).

The population without a migration background comprises mostly Swiss-born (99.5%), but also naturalized persons (0.4%) and foreign nationals from the third or a higher generation (0.1%).

With the exception of Swiss-born persons who have at least one parent born in Switzerland, all persons born abroad are considered as belonging to the first generation of persons with a migration background (about 2.2 million in the population aged 15 and over in 2019).

This group is composed of:

• foreign nationals born abroad (comprising slightly more than 70% of the group: 1,557,000);
• Swiss-born persons born abroad and whose parents were both born abroad (26,000);
• foreign-born naturalized persons (619,000).

The second generation, i.e. persons with a migration background born in Switzerland (520,000 individuals), is composed of naturalized persons (50%), foreign nationals with at least one parent born abroad (33%) and Swiss-born persons whose parents were both born abroad (17%).

Between 2014 and 2019, the permanent resident population aged 15 and over with a migration background increased (+2.1 percentage points), whereas the population without a migration background experienced a decrease (-3.3 percentage points). The increase since 2018 in the number of persons for whom some relevant data are unavailable is due to the fact that people aged 90 and higher have not been surveyed in the SLFS since 2018. Therefore, it is not possible to determine the nationality at birth of these persons; which is an indispensable information to construct the migration status.

In 2019, 60% of the Swiss permanent resident population aged 15 or over had no migration background. In comparison with 2018, this is a decrease of 0.7 percentage point.

An analysis of the generation status shows that the first generation has increased, whereas the second generation has slightly decreased (+1.7% and -0.2% in comparison with 2018). The analysis by nationality reveals that 80% of the growth in the number of persons with a migration background is attributable to citizens of EU28 and EFTA member states and to Swiss nationals (+29,000). The rise was less distinct for nationals of other European countries and from elsewhere in the world (+7,000).

By nationality

A breakdown of the population with a migration background by nationality shows that the most represented nationality is Swiss, corresponding to over a third of this population. The proportion of women with Swiss nationality is greater than that of men (41% and 32% respectively). The second most represented nationality among men is Italian. The second most represented nationality among women is German. The reverse holds true for the third position, with German nationality for men and Italian nationality for women. Portuguese nationality holds the fourth place for both sexes in the population with a migration background, followed by French nationality.

In the first generation, slightly less than half are citizens of EU28 and EFTA member states, almost 30% are Swiss, 11% are citizens of other European countries and 11% are from elsewhere in the world. In the second generation, more than 65% have Swiss nationality and almost 25% are from a EU28 or EFTA member state.

By age and sex

The permanent resident population shows different age pyramids depending on whether the persons with or without a migration background are being observed. The age pyramid of the population without a migration background resembles the age pyramid of the whole population in Switzerland. In contrast, in the population with a migration background, people are younger. The age groups between 25 and 50 are over-represented in relation to the population without a migration background. The average age of the population without a migration background is close to 50, whereas in the population with a migration background the average age is 45 years.

With regard to the old age dependency ratio (ratio between persons aged 65 or over and the working-age population between 20 and 64), it is more than twice as high (35) in the population without a migration background than in the population with a migration background (15).

Overall, regardless of migration status, the population is equally divided with regard to sex, with a small majority of women (51%) in comparison with men (49%). However, the second generation tends to have more men (52%) than women (48%).

Distribution among cantons

The distribution of the population by migration status is not spread evenly among the cantons. At national level, 38% of the Swiss permanent resident population aged 15 or over has a migration background. This percentage is higher than 60% in the canton of Geneva. The rates are also particularly high in the cantons of Zurich, Zug, Basel-Stadt, Ticino, Vaud, and Neuchâtel (40% and above). In contrast, the percentage of the population with a migration background is less than 20% in the cantons of Obwalden, Uri and Appenzell Innerrhoden (results from the two latter cantons, however, should be interpreted with caution as the extrapolations are based on fewer than 50 observations).

The first and second generations are not equally distributed between cantons. At the national level, the first generation represents 31% of the permanent resident population aged 15 and over; the second generation 7%. The ratio is, therefore, around 4:1. In certain cantons such as Uri and Graubünden, the ratio shows that the second generation is proportionally under-represented (ratio higher than 6:1). In contrast, in comparison with the national average, the second generation is over-represented in relation to the first generation in the cantons of Schwyz, Obwalden, Glarus, Solothurn, St. Gallen, Aargau, Thurgau, Ticino and Jura.

Persons younger than 15

It is not possible to determine the migration status of children under the age of 15 with FSO data. However, information can be obtained regarding their place of birth and nationality.

Almost three-quarters of the population aged under 15 is Swiss and was born in Switzerland. The remaining quarter was either born abroad (10%: 8% foreign nationals and 2% Swiss nationals), or born in Switzerland and of foreign nationality (19%).

Top ten nationalities

Children with a foreign nationality (more than 25% of the population aged under 15) are mainly Portuguese, German and Italian (13%, 12% and 11%, respectively). Children of Kosovan, French and North Macedonian nationality are also strongly represented among foreign nationals aged 0 to 14.

Age pyramid and sex

Depending on their place of birth, the age pyramid for children under 15 has a different shape: it is rectangular for those born in Switzerland and an inverse pyramid for those born abroad. There are no large differences between girl and boy populations by age and country of birth.

Children according to migration status of household

Data cumulated from the years 2014 to 2016 show that half of children aged 0 to 14 were living in a household with no migration background (44% of 0-6 year-olds and 47.3% of 7-14 year-olds). A third of them were living in a household with a migration background (35%). 21.0%% of children aged 0 to 6 lived in a household with a mixed migration/non-migration background (i.e. comprising persons with and without a migration background). This is a higher percentage than for children aged 7 to 14 where the figure is 17%. The younger the children are, the more likely they are to live in a mixed household (see indicator “Private households by type”). For more information on defining the migratory status of the household, see the 'Definitions' tab below.

Definitions

A household’s migration status is established as follows:

The household has no migration background if neither the father nor mother alone, nor both members of a couple (with or without child(ren)) nor any person in a non-family household or other type of household is not born abroad or does not have a foreign nationality. The household has a migration background if the father or mother, or both members of a couple (with or without child(ren)) or all people in a non-family household or other type of household are born abroad or have a foreign nationality. The household has a mixed migration background if one of the two members of a couple (with or without child(ren)) or at least one of the persons in a non-family household or other type of household is born abroad or has a foreign nationality and the other(s) does/do not.
