In last year's survey, which covered 133 countries, Croatia received a mark of 3.7 and was placed 59th as the year before.
"The situation is not good. Croatia is starting to lose the battle against corruption," TI Croatia president Zorislav Antun Petrovic said presenting the survey.
He explained that the latest mark, which is only slightly poorer than last year's, was not the only reason for concern. Another reason is the four-year declining trend, he said. The survey has been conducted in Croatia since 1999, and in 2000 the country's mark improved from 2.7 to 3.9.
Croatia shares its position with Peru, Poland and Sri Lanka.
The results of the survey on the corruption perception index for 2004 were published by all national TI organisations.
