The data are expressed in Purchasing Power Standards (PPS) which allows the elimination of the differences in price levels that exist between countries and facilitates, therefore, a comparison of the GDP that better reflects the economic capacity of the citizens of each country.
The volume of GDP per capita in Purchasing Power Standards is expressed in relation to the average of the European Union (EU-28), which takes the value of 100. Thus, if a country’s index is higher than 100, it means that the GDP per capita level of that country is higher than the average value of the European Union, and vice versa.
