Migration is the main driver of demographic trends in Switzerland
Net migration and total variation of Swiss population (thousands of people) in Switzerland per year since 1950. The population has grown from 4.7 million residents in 1950 to 9 million today.
Definitions: net migration is the difference between immigration and emigration; the remaining population variation results from natural variation, i.e. the difference between the number of births and the number of deaths.
