According to Transparency International's International Corruption Perceptions Index 2015, India is placed at 76th position along with Thailand, Brazil, Tunisia, Zambia and Burkina Faso out of 168 countries.
India has improved its past year's position of 85 and has a grade index score of 38 out of a possible 100 which indicates the least corrupt, said the report topped by Denmark.
The index was prepared by using data from institutions including the World Bank, the African Development Bank.
"Not one single country, anywhere in the world, is corruption-free," the report said.

"The 2015 Corruption Perceptions Index clearly shows that corruption remains a blight around the world. But 2015 was also a year when people again took to the streets to protest corruption. People across the globe sent a strong signal to those in power: it is time to tackle grand corruption," said Jose Ugaz, Chair, Transparency International, global watchdog on graft and abuses of power.
The US rose one spot this year to 16th place with a score of 76, tying with Austria. The UK rose three spots to place 10th, with a score of 81 that tied it with Germany and Luxembourg.
The other top spots, from second to ninth, were occupied by Finland, Sweden, New Zealand, the Netherlands, Norway, Switzerland, Singapore and Canada.
Brazil and Turkey were among nations that tumbled the most. Brazil slid to 76th place, sharing its position with India, down from 69th last year. Turkey fell two spots to 66th, continuing its descent from 53rd place in 2013.
"Corruption can be beaten if we work together. To stamp out the abuse of power, bribery and shed light on secret deals, citizens must together tell their governments they have had enough," Ugaz said.
Global corruption index, a composite index that draws from 12 surveys to rank nations around the globe, has become a benchmark gauge of perceptions of corruption and is used by analysts and investors.
