Why are some countries no longer reported in the CPI, and why are new countries included?
TI requires at least three sources to include a country in the CPI. The change in country coverage in the CPI 2006 relates to the fact that a new source, the World Bank’s Country Policy and Institutional Assessment (CPIA) has been included, while two sources (Columbia University’s State Capacity Survey and Information International’s Survey of Middle Eastern Businesspeople) are now more than two years old and have been dropped from this year’s CPI. The omission of these older surveys has resulted in the following countries being removed from the CPI: Afghanistan, Fiji, Liberia, Palestine and Somalia. The inclusion of the CPIA and the increase of country coverage by PERC, however, have allowed the TI CPI 2006 to include the following new countries: Bhutan, Central African Republic, Dominica, Timor-Leste, Grenada, Guinea, Macau, Mauritania and Togo.
