Switzerland has a population of 8.02 million as of 2012. Its population has quadrupled over the period 1800 to 1990 (average doubling time 95 years). Population growth was steepest in the period after World War II (1.4% per annum during 1950-1970, doubling time 50 years), it slowed down during the 1970s to 1980s and has since again picked up to 1% during the 2000s (doubling time 70 years).

More than 75% of the population live in the central plain, which stretches between the Alps and the Jura Mountains and from Geneva in the southwest to the Rhine River and Lake Constance in the northeast. Resident foreigners and temporary foreign workers make up about 20% of the population.

Encompassing the Central Alps, Switzerland sits at the crossroads of several major European cultures. Its population includes a two-thirds majority of Alemannic German speakers and a one-quarter Latin minority (French, Italian and Romansh), see linguistic geography of Switzerland. 10% of the population natively speak an immigrant language.
