Identification of prospective industrial clusters in Slovakia

underestimated. The manufacture of basic metals was rather stable in time, while the manufacture of other non-metallic mineral products was not considered a cluster candidate in recent years. On the other hand, in 2015 and 2016, the manufacture of pharmaceuticals emerged among potential clusters. According to Fig. 2 , this industry was not presented in previous years because similarly to the case with the forestry, the related employment data in the Banská Bystrica region was not published by the Statistical Office of the Slovak Republic due to some confidentiality reasons
