There is an increasing demand from developing country governments, civil society organisations and donor agencies to measure different aspects of democracy, human rights and governance. This demand has resulted in a tremendous growth in indicator sources, which are used to measure the performance of governments, the quality of public institutions, as well as people's perceptions of various aspects of governance. This publication will equip users to make sensible use of sources of governance indicators, as this publication aims to bring together both 'where to find' and 'how to use' material on these sources.
