The permanent resident population is the reference population for population statistics.
As of 2010, the permanent resident population includes:
• all Swiss nationals having their main place of residence in Switzerland;
• foreign nationals who have held a residence or permanent residence permit for a minimum of 12 months (permits B,C, L, F or N or FDFA permit-holding international civil servants, diplomats and their family members).
This definition corresponds to the international recommendations for population statistics. The obtained data can be used in the compilation of statistics on the Swiss and foreign resident population.
The population evolves due to certain demographic movements (births, immigrations, deaths and emigrations).
