At the end of 2025, 9,124,300 people were permanently resident in Switzerland, representing an increase of 0.8% (+73,300 people) compared with the previous year, the Federal Statistical Office said in a statement. However, this increase was lower than that recorded in 2024.
The population increased in all cantons. The strongest growth was recorded in Schaffhausen (+1.6%), Basel-City (+1.4%) and Valais (+1.3%). Glarus and Ticino were at the bottom of the table (+0.2%), followed by Bern, Jura and Neuchâtel (+0.4%).
The number of older people exceeds that of young people for the first time (1,811,000 people aged 65 or over, compared with 1,802,000 people aged under 20). Each of these two age groups accounts for around 20% of Switzerland’s total population.
Life expectancy is projected to reach 86.3 years for women and 82.7 years for men in 2025.
Births are falling, deaths are stagnating
Births continue to fall, but at a slower rate (-0.5% in 2025 compared to -2.2% in 2024). The provisional average number of children per woman stood at 1.28 in 2025. A decline in births is observed in 18 of the 26 cantons compared with 2024, according to provisional figures. They are rising in the cantons of Appenzell, Nidwalden, Geneva, Basel-City, Vaud, Solothurn and Schaffhausen.
