Net rent comes from the 2022 census (reference date 15 May 2022) and covers every rented home, including long-standing tenancies, so it is usually lower than the asking rents in new listings.
Figures for municipalities, districts and states are built up from the census 100-metre grid cells, with rents weighted by the number of homes. Vacancy and owner-occupation rates come from the one-kilometre grid, as they are mostly withheld in the 100-metre cells.

Police crime statistics count offences that became known to the police and were fully processed by them, by place of offence. The rate relates them to the resident population, so cities with many commuters, visitors and shops show higher rates. Offences against residence and asylum law and drug offences are not shown here; drug offences mostly reflect how actively the police carry out checks.
