Red Hat Inc. has released the Open Source Index, a study undertaken by Professors Noonan and Baker in the School of Public Policy and Center for
Advanced Communication Policy at the Georgia Institute of Technology. The index compares and contrasts open source activity and environment across 75 countries.

The global growth of open source continues to increase across the private sector, government and individuals. Red Hat presents this study to the community as a framework and tool for furthering the interest and understanding of open source adoption. The study measures open source using two separate indices: one for activity and another for environment. The activity index measures the amount of open source currently present in a country and includes concrete factors such as existing open source and open standards policies and the number of open source software users or producers.

The environment index includes factors at a country level that may further, or coexist with, open source activity such as a high number of Internet users.
