Swedish as a mother tongue
Sweden does not have an official statistics on home language. The closest register measurement is the school system’s entitlement to mother-tongue instruction. This page explains what that measure shows, what it doesn’t show — and why the difference matters.

Four registers — do not conflate them
‘Mother tongue’ means four different things
1 · Administrative
Entitlement to mother-tongue instruction in Sweden’s school system. Register-based, guardian-reported. This is what most Swedish statistics measures.
Skolverket.
2 · Linguistic
The first language(s) acquired in early childhood. Not measured in official Swedish statistics.
Language research standard definition.
3 · Everyday dominant
The language a person uses most in everyday life. Not measured in official statistics; occasional surveys.
Language Council of Sweden.
4 · Self-identified
The language a person identifies with, regardless of proficiency. Not measured in official statistics.
Concept from sociolinguistics.
The Skolverket indicator on this page measures register 1. Do not use it as a substitute for the other three.
What the numbers say
| School year | Swedish at home | Entitled to mother-tongue instr. |
|---|---|---|
| 1995 | ≈ 88 % | ≈ 12 % |
| 2005 | ≈ 82 % | ≈ 18 % |
| 2015 | ≈ 76 % | ≈ 24 % |
| 2020 | ≈ 72 % | ≈ 28 % |
| 2023/24 | ≈ 70 % | ≈ 30 % |
Read: in 1995 around 88 % of pupils had ‘Swedish at home’ per Skolverket’s register. In 2023/24 the share was around 70 %. Rounded values, method notes see Skolverket.
Why Sweden has no official home-language statistics
In several other countries the population register or the census records language. In Finland language is a register attribute (Finnish, Swedish, Sami, other). Switzerland measures main language via the annual structural survey. In Sweden the population register records only citizenship and country of birth, not language. This is a deliberate choice going back to the 1975 minority policy — language and ethnicity should not be linked to the individual in the register. The consequence is that we have no consistent time series for the adult population; the school system is where the most systematic time series happens to sit.
The Language Council of Sweden estimates that around 150 languages are spoken in Sweden today, and that around 20 % of the population has a home language other than Swedish. These are estimates, not measurements.
What does the data show?
Objective observations — not interpretations
- The share of pupils registered as having Swedish as the only daily home language has fallen from around 88 % (1995) to around 70 % (2023/24).
- The measure is administrative: it captures entitlement to mother-tongue instruction, not language proficiency.
- Sweden has no official statistics on home language for the adult population — only school-system data and survey estimates.
- The Language Council of Sweden estimates ~150 languages are spoken in Sweden and ~20 % of the population has another home language than Swedish.
