Purchasing power parities (PPPs), price level indices and real expenditure

Purchasing power parities (PPPs) are indicators of price level differences across countries. The PPPs are calculated by Eurostat and the OECD with the price and expenditure data that countries participating in the Programme supply specifically for the calculation.

Dedicated section on PPPs is published in Eurostat website.

Eurostat publishes wider coverage of analytical categories and indicators. The published results are available on the Eurostat homepage.

PPPs are spatial price level indicators, and thus primarily suitable in comparisons referring to several geographical locations at a given point in time. 

N/A

Data required for PPP calculations on general government expenditures for education are extracted by Eurostat from the UNESCO-OECD-Eurostat database (once per year).
Basic information for PPP calculations is provided by surveying retail outlets, service provision sites and conducting sample surveys of enterprises. Calculations are made using data available to institutions.

N/A

Eurostat carries out calculations every year. The peculiarity of the respective surveys hides in the correlation of the information provided by the countries involved in the comparisons and its impact on the results. Unlike in other statistical surveys, an individual country may not obtain comparison results on its own, and changes in the data of one country also affect the results of other countries.

Eurostat calculates and publishes the final annual results no later than 36 months after the end of the reference year.
