The 2000 Corruption Perceptions Index covers 90 countries, compared to 99 last year. Some countries had to be dropped because there was insufficient 1998-2000 data. For example, some of the surveys used in the CPI are based on international investor attitudes and if a country is widely seen to no longer interest investors, then some survey sources may drop that country in their polling. The message is clear: dropping out of the CPI for lack of data may be bad news for countries and may indicate reduced investor interest stimulated by enhanced perceptions of widespread corruption in these countries.
We all yearn for improvement, but positive change only comes slowly when the enemy is endemic corruption. Perceptions of levels of corruption do not change greatly from one year to the next. Positive results are only going to emerge from tireless and consistent multi-year efforts.
