Abstract
The aim of this study is an analysis of the dynamics of change in the number of tourists who used Polish hotel services in the years 2009-2015. For this evaluation data from the Central Statistical Office of Poland were used. The obtained data pertaining to the number of both Polish and foreign tourists were analysed in an absolute and a relative (percentage) scale. The results shown in a relative scale provide a better picture of the dynamics of change in the processes as all values are assigned an initial value: P0 = 100 percent. They therefore informs what was the dynamics of growth in the initial 100 tourists who used Polish hotel services in the years 2009-2015.
