The survey was carried out in December 2001. 1008 respondents were involved in research all over Estonia. The objective of this project was to investigate how people understand corruption in the society and the distribution of corruption, and also to compare how these changed in comparison to a previous survey conducted in 1998. Results indicated that respondents have quite an adequate understanding about corruption and corruptive behaviour. Accordin to the results, the biggest change occured among people who had some kind of contact with corruption - number of respondants who experienced corruption decreased. In 1998 the percentage of respondants with no personal contact with corruption was 69,4%, whereas in 2001 it was 83,5%. This decrease was identified especially in the category of people with occasional contact with corruption (17,7% in 1998 and 6,1% in 2001); the percentage of individuals with frequent contact with corruption remained largely the same.
