World Development Indicators 2008
Release of the final report of the International Comparison Program (ICP) and publication of new estimates of purchasing power parities (PPPs) in World Development Indicators 2008 are an important statistical milestone. The estimates offer a consistent and comprehensive set of data on the cost of living in developed and developing countries, the first since 1997, when the results of the previous ICP data collection were published in World Development Indicators. The 2005 data cover 146 countries and territories, 29 more than the last round in 1993, and many for the first time.
