Switzerland
Demographics

In common with other developed countries, the Swiss population increased rapidly during the industrial era, quadrupling between 1800 and 1990 and has continued to grow.

The population is about 9 million (2023 est.). Population growth was projected into 2035, due mostly to immigration. Like most of Europe, Switzerland faces an ageing population, with a fertility rate close to replacement level. Switzerland has one of the world's oldest populations, with an average age of 42.5 years.

According to the World Factbook, ethnic groups in Switzerland are as follows: Swiss 69.2%, German 4.2%, Italian 3.2%, Portuguese 2.5%, French 2.1%, Kosovan 1.1%, Turkish 1%, other 16.7% (2020 est). The Council of Europe figures suggest a population of around 30,000 Romani people in the country.
