Until January 1, 2015 it was named the Inner Carniola–Karst Statistical Region[6][7][8] (Slovene: notranjsko-kraška statistična regija).

[9] The karst terrain, with Postojna Cave and intermittent Lake Cerknica, is the most important natural feature of this statistical region.

The region is among the economically less developed ones in the country because in 2012 it contributed only 1.8% of Slovenia’s GDP.

With an average of four employees per company, the enterprises in the region are among the smallest in Slovenia.

In 2013, the average utilised agricultural area per farm was the highest in this region.
