The region of wooded hills and three river valleys lies in the northern part of the country along the border with Austria. As regards traffic, it is difficult to access and is badly connected with the central part of Slovenia.
The environment has been strongly affected by the heavy industry in the valleys. Manufacturing, mining and quarrying created the highest share of gross value added in the region in 2008. The importance of agriculture in the region is presented by the largest agricultural holdings in terms of their average economic size, in terms of utilised agricultural area and in terms of the number of livestock units. In addition, agricultural holdings in the region also manage the largest average forest areas.
The population of this region is in terms of the mean age younger than that of the majority of Slovenian regions. The population age structure is favourable since the share of people aged 65 or more is among the lowest in Slovenia. In 2009 the value of the ageing index, which describes the ratio between the population aged 65 or more and the population aged under 15, was in Koroška 112.2, meaning that there were 112 older people per 100 young people.
The marriage rate in the region has traditionally been below the national average and according to data for 2009 already seven out of ten newborns were born outside marriage, which was the highest share among the regions.
