Statistical data are managed by numerous authorities, organizations, etc. The competent institution for the Republic of Croatia is the Croatian Bureau of Statistics. The CBS is a state administrative organization, central agency, main holder, disseminator and coordinator of the official statistical system of the Republic of Croatia. It covers all important strategic areas on the basis of the current social and economic situation in Croatia. Unlike the CBS, Eurostat is the European statistical institution whose mission is to provide quality statistical analyzes throughout Europe. Eurostat aims to provide insight into a deeper understanding of the lives of Member States and non-EU countries. 39 The tabular comparison shows that the CBS lags behind Eurostat in terms of more detailed data, and the reason is that Eurostat is an institution that disposes and collects data throughout Europe, so the analysis is more detailed. An example is the area of Tourism, where there is an obvious difference in the amount of data available to the CBS and Eurostat. Eurostat has data at a more detailed level compared to the CBS, but it can be said that the CBS is progressing in its direction by approaching European standards. Among other things, statistical harmonization refers to the harmonization of the Croatian official statistical system with the European Statistical System, coordinated by the European Commission and Eurostat. In general, it can be stated that a good level of compliance has been achieved.
