This statistical 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 created the highest share of gross value added in the region in 2009. The importance of agriculture in the region is presented by the largest agricultural holdings in terms of their average size of utilised agricultural area and in terms of the number of livestock units. Regarding the average age, managers of agricultural holdings in Koroška were the youngest (53 years); they were on average eight years younger than managers of agricultural holdings in the Notranjsko-kraška region.

The population of this region is in general younger than that of the majority of Slovenian regions according to their mean age. The population age structure is favourable since the share of people aged 65 or more is among the lowest in Slovenia. In 2010 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 114.4, meaning that there were 114 older people per 100 young people. In Koroška every fifth family is an unmarried couple family; the share of children born in this type of family was with 71% also in 2010 the highest among regions.
