Centre zone density increases
There has been no major change in the centre zone area over the last three years, while the number of residents has increased throughout the period 2007-2012, leading to a density increase in the centre zones. The number of employees has fallen slightly in the last four years.
People are increasingly choosing to live in urban areas. It is also a political goal to utilise the urban areas as intensely as possible in order to ease the pressure on the surrounding land and at the same time minimise the need for transport.
While the number of employees decreased somewhat in 2009 and 2010, 2011 saw an increase. The density increase continued for residents. Nevertheless, centre zones have around twice as many employees as residents.
High density of residents is an indicator for effective land use utilisation as well as less energy-demanding transportation. High density of residents can, on the other hand, indicate poor dwelling conditions, scarcity and pressure on green areas.
The density in centre zones increase by urban settlement size. There are more employees than residents per square kilometre in all size groups. The largest cities have almost 6 times as many employees and residents per km2 compared to small urban settlements. Only the biggest cities have had growth in area, residents and employees over the last five years. The density of residents has increased in all size groups, while density of employees has increased in the 20 000-100 000 size group only.
The different group sizes do not necessarily include the same urban settlements. Urban settlement growth can lead to a shift towards the upper group sizes, while small settlements can fall below the definition criteria and be omitted.
