 abstract={The aim of the paper was to determine wage inequalities between the PKD sections in Poland. The research was based on the data on average wages published by Polish Central Statistical Office in 2009 and 2018. Descriptive statistics were used as well as statistical significance tests to compare the data. All hypotheses were verified positively. Wage inequalities occurred between all the PKD sections. In 2018 they were lower than in 2009. At the same time the phenomenon was changeable. Furthermore, with the use of the Wilcoxon signed-ranked, it was concluded that wage inequalities in 2009 and 2018 were similar.},
