The Open Data Barometer aims to uncover the true prevalence and impact of open data initiatives around the world.

It analyses global trends, and provides comparative data on countries and regions via an in-depth methodology combining contextual data, technical assessments and secondary indicators to explore multiple dimensions of open data readiness, implementation and impact. The 2014-15 edition of the Open Data Barometer examines open data readiness, implementation, and impact across 86 countries, and provides a country ranking based on scores in each of these three categories.
