How is foreign background measured?

Sweden, Denmark and Germany define migration and foreign background differently. The difference determines who falls inside or outside the category — and therefore how large the population share becomes. Each country's official definition is shown here, with source, version and what may be compared.

Short answer: the definitions differ in three ways — whether citizenship is included, how many parents are required, and whether there is a cut-off date for immigration. A definitional difference can therefore change a population measure, but it can never be used to derive crime, costs or net contribution figures.

Official definitions, country by country

The texts below follow each statistical agency's own wording. The shares refer to each country's own population and are taken from the publication indicated.

SCB — Statistiska centralbyrån

Sweden

Persons with a foreign background are those born abroad and those born in Sweden with two foreign-born parents.

Second generation
Only when both parents are foreign-born. Persons with one Swedish-born and one foreign-born parent are classed as having a Swedish background.
Published share
26,5 % (2023)
Version
MIS 2002:3 (gäller fortfarande)
Comparability
Based solely on country of birth. Citizenship is not part of the criterion.
SCB — Personer med utländsk bakgrund (MIS 2002:3)

Danmarks Statistik (DST)

Denmark

Immigrants: persons born abroad where neither parent is both a Danish citizen and born in Denmark. Descendants: persons born in Denmark where neither parent is both a Danish citizen and born in Denmark. Persons of Danish origin: persons — regardless of birthplace — with at least one parent who is both a Danish citizen and born in Denmark.

Second generation
Yes — 'efterkommere' (descendants) are reported as their own group, but only when neither parent is both a Danish citizen and born in Denmark.
Published share
14,4 % (1 januari 2022)
Version
Herkomst-typologi, dokument daterat 2024-09-20
Comparability
Combines country of birth AND citizenship. Differs from Statistics Sweden, which uses country of birth only — the same person can be classified differently.
Verification: PARTIAL
The definition is verified against DST's own definition document (20 Sept 2024). The share refers to 1 January 2022 — DST's live page shows a higher current share, but its exact reference period could not be verified against the underlying table and is therefore not reported here.
Danmarks Statistik — definition av indvandrere, efterkommere og personer med dansk oprindelse (2024-09-20)

Statistisches Bundesamt (Destatis)

Germany

The definition covers all persons who either themselves (immigrants) or whose both parents (descendants of immigrants) immigrated to present-day Germany since 1950.

Second generation
Yes — but only when BOTH parents immigrated since 1950. The third generation is not included.
Published share
25,6 % (2024)
Version
Mikrozensus 2022 och framåt (första publicering 2023)
Comparability
Narrower than the older Migrationshintergrund concept and not comparable with it. The requirement that BOTH parents immigrated resembles Sweden's two-foreign-born-parents rule, but Germany also applies a 1950 cut-off and counts immigration rather than country of birth alone.
Series break
Series break: the concept was introduced in the 2022 Mikrozensus and first published in 2023. Destatis states explicitly that the new definition is narrower than Migrationshintergrund — the series are not comparable. The 2022 census also re-based the population denominator.
Destatis — Hintergrundpapier: Einwanderungsgeschichte

Method context: Germany's older concept

A person has a migration background if they themselves or at least one parent was not born with German citizenship. Broader than both Einwanderungsgeschichte and Sweden's foreign background: one parent suffices, and the criterion is citizenship at birth rather than country of birth. Not directly comparable with Swedish or Danish figures. Published in parallel with the newer Einwanderungsgeschichte concept since 2023. The two measures cover different populations.

Destatis — Glossar: Migrationshintergrund

Comparison: three statistical systems

The table shows who is counted, how the second generation is handled and the share each agency publishes. The shares refer to different populations and different reference periods — they are not the same measure taken three ways.

Sweden

Who is counted?
Persons born abroad or Persons born in Sweden with two foreign-born parents
Second generation
Only when both parents are foreign-born. Persons with one Swedish-born and one foreign-born parent are classed as having a Swedish background.

Who is counted?
Indvandrere (born abroad per the criterion above) or Efterkommere (born in Denmark to two parents who do not both meet the Danish-citizen-and-born-in-Denmark criterion)
Second generation
Yes — 'efterkommere' (descendants) are reported as their own group, but only when neither parent is both a Danish citizen and born in Denmark.

What the choice of definition affects — and does not

Switch between countries in the box below. The definition changes the explanation and shows the country's own published population share. Swedish values are never converted to another definition — neither population, crime nor costs. Such a conversion would require separate, verified data that has not been published.

Population with foreign background

2,77miljoner

Swedish definition (SCB)

Number of persons (millions) per SCB's definition. Applies to Sweden and is not converted.

Share of Sweden's population

26,5%

Swedish definition (SCB)

Share with foreign background per SCB's definition.

What it means

Based solely on country of birth. Citizenship is not part of the criterion.

Share of the population according to the country's own statistics

26,5 % (2023) refers to Sweden's population.

Second generation

Only when both parents are foreign-born. Persons with one Swedish-born and one foreign-born parent are classed as having a Swedish background.

The definitions are not conversion keys. Shares refer to each country's own population and own statistical definition. Swedish outcome figures — crime, costs, net contribution or welfare dependency — are never converted to another definition; such comparisons require separate, verified data.

Baseline (SE definition): 2,77 milj. with foreign background (SCB, Utländsk bakgrund 2023) · 26,5 % of the population (SCB). Crime and cost measures are not included: they cannot be derived from a definition's breadth.

What the difference means for population measures

  • The number of parents matters. SCB and Destatis require that both parents meet the criterion; Denmark requires that neither parent is both a Danish citizen and born in Denmark. The same person can therefore be classified differently.
  • Citizenship is included in some systems. Sweden uses only country of birth. Denmark factors in citizenship, and Germany's older concept was based entirely on citizenship at birth.
  • The third generation is not counted anywhere. None of the three systems tracks grandchildren of immigrants as a separate category in the headline measure.
  • Outcomes require their own data. Crime, costs, net contribution and welfare dependency do not follow from a definition's breadth. Such comparisons require data collected on the respective definition — if it does not exist, it is reported as a missing data point.

Method rule

The definitions are not conversion keys. Shares refer to each country's own population and own statistical definition. Swedish outcome figures — crime, costs, net contribution or welfare dependency — are never converted to another definition; such comparisons require separate, verified data.
