Open Knowledge has published the 2014 Open Data Index.
Here's an excerpt from the announcement:
The Index ranks countries based on the availability and accessibility of information in ten key areas, including government spending, election results, transport timetables, and pollution levels.
The UK topped the 2014 Index retaining its pole position with an overall score of 96%, closely followed by Denmark and then France at number 3 up from 12th last year. Finland comes in 4th while Australia and New Zealand share the 5th place. Impressive results were seen from India at #10 (up from #27) and Latin American countries like Colombia and Uruguay who came in joint 12th.
