The Longitudinal demographic statistics (DVS) are based on the population data from STATPOP. They started on 31.12.2010 and comprise all people in the permanent and non-permanent resident population who have appeared at least once in STATPOP (population stocks or flows). The DVS end with the latest available STATPOP data and are thus completed and fully updated every year. For this reason, it should be noted that numbers from the DVS may vary from those of STATPOP. For the annual population numbers of the permanent and non-permanent resident population, the annually published results of STATPOP are final. Explanations for the DVS methodology can be found in the document «Produktionsregeln und Ergebnisse» (in German and French).
Around 11 million entries of persons were counted up to 2022. Between 2011 and 2022, nearly three-quarters of these persons neither immigrated nor emigrated.
51% of the Swiss nationals who emigrated in 2011 had returned to Switzerland by 2022; two-thirds of them had already done so in the first three years following their emigration. Among foreign nationals in the same period, the rate of return was only 17%. Foreign nationals born in Switzerland are more likely to return than those born abroad.
