Population density

from Wikipedia, the free encyclopedia

When population density is an adjusted form of population density . The population of an area is only related to the theoretically or actually populated area. Areas that cannot be inhabited due to natural characteristics (e.g. deserts , bodies of water ) or legal provisions (e.g. nature reserves , military restricted areas ) are excluded from the settlement density.

In regions in which the permanent settlement area only makes up a small part of the total area (e.g. mountain regions), the settlement density is much more meaningful than the population density. In the state of Tyrol , for example, the permanent settlement area comprises only 12.5% ​​of the total area, the settlement density is 459 inhabitants / km² compared to a population density of 57 inhabitants / km² (as of 2014).

The theoretically colonizable or actually inhabited areas can be determined, for example, on the basis of a land use plan that shows the areas intended for residential development. Other assessment bases are aerial photographs and population registration data .

Urban pressure

In areas with a high or steadily growing population density due to influx , especially metropolises , one often speaks of so-called settlement pressure. The increasing urbanization of society leads to such high settlement pressure in large cities that rents and square meter prices are sometimes hardly affordable for normal consumers. High settlement pressure in cities leads to both densification and, if there is insufficient control, to urban sprawl in the peripheral areas. It thus constitutes a factor that conflicts with urban ecology , the preservation of local recreation areas and urban or urban biotopes .
