The publication presents the detailed results of the 2011 International Comparison Program (ICP). The ICP is a worldwide statistical initiative that aims to estimate Purchasing Power Parities (PPPs) to be used as currency converters to compare the size and price levels of economies around the world. The program involved 199 economies from eight geographic regions: Africa, Asia and the Pacific, Commonwealth of Independent States, Latin America, the Caribbean, Western Asia, Pacific Islands, and the countries of the regular PPP program managed by OECD and the Statistical Office of the European Communities (Eurostat).
