The Purchase Power Parity (PPP) represents the quantity of local currency units required to buy goods or services in the local market, as one dollar would do in the United States market (using that country as reference). In that way, PPP measures involve the exchange rate, as well as the relative prices index of each country.

The main objective of PPP measures is to obtain the real values for the comparison of the GDP and S&T expenditure between countries.

All these tables will be published in the new edition of de annual report “El Estado de la Ciencia 2003”.
