Classification of Economic Regions with Regards to Selected Factors Characterizing the Construction Industry

This article presents the methodology for classifying economic regions with regards to selected factors that characterize a region, such as: the economic structure of the region and share of individual sectors in the economy; employment; the dynamics of the development of individual sectors expressed as an increase or decrease in production value; population density, and the level of occupational safety. Cluster analysis, which is a method of multidimensional statistical analysis available in Statistica software, was used to solve the task. The proposed methodology was used to group Polish voivodeships with regards to the speed of economic development and occupational safety in the construction industry. Data published by the Central Statistical Office was used for this purpose, such as the value of construction and assembly production, the number of people employed in the construction industry, the population of an individual region, and the number of people injured in occupational accidents.
