The 'Year in Elections' report, compiled by an independent research group affiliated with Harvard University and the University of Sydney, has Denmark at number one after analysis of 180 presidential and parliamentary elections during the period July 2012 to December 2015.
The Electoral Integrity Project (EIP) compiled its list by gathering data from over 2,000 election experts through global surveys. The surveys use a number of indicators which are grouped into several stages of election cycles, taking into account factors like fairness of media coverage, campaign financing and social constraints on fair voting.
The numbers are eventually crunched together to form what the research group terms the Perception of Electoral Integrity, a score between 1 and 100.
With a score of 86, Denmark beat every other country included in the study.
Interior Minister Karen Ellemann said that the report is "a world championship Denmark can be proud of".
“When we receive this kind of recognition from a group of experts, we ought to pat ourselves on the back,” Ellemann told Ritzau.
“We should be proud that we have the highest degree of integrity measured by international standards and norms for elections,” she continued.
All Nordic countries fared well in the study, with Finland, Norway and Sweden coming just behind Denmark and Iceland placing at number 10.
But some surprisingly low scores – including that of the United Kingdom, which ranked 39th overall following its 2015 general election; and the 47th-ranked United States, whose 2012 Presidential election and 2014 Congressional election were, according to the report, "ranked worst of any long-established democracy" – show that Denmark's high-ranking score is not achieved simply by virtue of being a Western democracy.

The five worst countries are:
