The phenomenon of corruption is known all over the world, and its intensity varies according to economic, behavioral and educational factors. Transparency International is a global civil society that carries out regular opinion surveys and publishes the perceptions of corruption in countries around the world. This index identifies the level of corruption perceived in the world and contributes achieving a ranking of countries in this regard. The corruption perception index should be correlated with economic situation of a country. The economic situation of a country can be reflected by GDP and unemployment rate. The purpose of this study is to determine whether the index of corruption is influenced by the economic situation of a country, so the study analyses the corruption perception index, GDP and unemployment rate, establishing whether there is a link between them.
