Data on corruption in Venezuela I'm trying to find some data on the level of corruption in Venezuela, since Chavez came to power, and its evolution along time. I've searched the world bank, but they don't seem to have this data on Venezuela...
The Corruption Perceptions Index of Transparency International could work for you. Chavez was in power from 14 April 2002 – 5 March 2013 and the index is available from 1995-2015 and includes Venezuela. In addition to the cross-country data, there is a more detailed Venezuela page produced by Transparency International.
