The Bertelsmann Transformation Index (BTI) is a measure of the development status and governance of political and economic transformation processes in developing and transition countries around the world.[2][3] The BTI has been published biennially by the Bertelsmann Stiftung since 2005,[4] most recently in 2022 on 137 countries.[5] The index measures and compares the quality of government action in a ranking list based on self-recorded data and analyzes successes and setbacks on the path to constitutional democracy and a market economy accompanied by sociopolitical support.[6] For this purpose, the "Status Index" is calculated on the general level of development with regard to democratic and market-economy characteristics and the "Management Index" on the political management of decision-makers.[7][8]
