Mr. Raj

Thank you so much.

You could also check out the World Governance Indicators - they have a corruption indicator which "captures perceptions of the extent to which public power is

exercised for private gain, including both petty and grand forms of corruption, as

well as “capture” of the state by elites and private interests". 

You can download the data there, or visualise the indicator on a map here by selecting:
