Tourism as the basic concept of this work is closely related to the concept of tourist as a person who represents a central figure, and can be described as a subject who travels outside his own place of residence in order to satisfy his own needs, which can be diverse. The meeting of tourist supply and demand, in which the tourists have the main say, takes place on the tourist market. Various factors affect the level of supply and demand, and harmony among market entities is necessary for quality functioning. Tourism can be divided into a large number of different types depending on certain factors, and within each form of tourism we distinguish natural and social tourism resources that can be evaluated according to selected elements. Tourism in the Republic of Croatia can be viewed separately through three areas, namely the Adriatic, mountain and Pannonian-Peripannonian tourist areas. According to the tourism results achieved in 2019, the Republic of Croatia has the greatest abundance of private and hotel accommodation, and tourists are mostly residents of Central European countries and countries with which the Republic of Croatia shares a border.
