In Statistics Sweden’s statistics, a locality refers to a continuous settlement with at least 200 inhabitants. Statistics Sweden delimits localities geographically and statistics are based on these localities. Settlement density is measured using digital maps from Lantmäteriet that contain information on buildings, properties, roads and land. The distance between buildings in a locality varies based on several factors, including the number of people in the population register and employees in the various parts of the locality. The largest possible distance is 500 metres. Information on population and employees is collected from Statistics Sweden’s register and is combined with information on addresses.
