TI publishes 2013 CPI: TI has published the 2013 Corruption Perceptions Index (CPI). Denmark and New Zealand top the table of "clean" nations, with a score of 91 on the index (where 0 is highly corrupt and 100 very clean). Most significant economies are in the top 20, including Switzerland (7), Canada (9), the UK (14) and US (19). Most of western Europe scores well, as do Australia and Japan. As usual, corruption is perceived as worst predominantly in Eastern Europe, Africa and many parts of South America. Only 54 out of the 177 countries surveyed score 50 or above. Afghanistan, North Korea and Somalia continue at the bottom of the table, with a score of 8. (Source: TI Publishes 2013 CPI)
