How we measure this

BFS

Change in the permanent resident population during calendar year 2025, in percent of the population on 1 January, from the FSO statistics on natural population movement (BEVNAT) and migration. A positive value means growth, a negative one decline. The percentage makes small and large municipalities comparable.
