On the basis of the census determined number of inhabitants with Hauptwohnsitz, the municipality receives its budget from the federal government.
Hauptwohnsitze count themselves for a municipality in two regards: By the direct payment per head, and an increase in premiums after exceeding certain thresholds for the number of inhabitants.
