Measuring corruption is essential for understanding its causes, consequences, and trends, as well as for designing and evaluating effective responses. By developing reliable and comparable indicators and data, we can enhance transparency, accountability, and evidence-based policymaking in the fight against corruption.

From 2 to 4 December 2025, the United Nations Development Programme (UNDP), the United Nations Office on Drugs and Crime (UNODC), and the International Anti-Corruption Academy (IACA) are convening the Second Global Conference on Harnessing Data to Improve Corruption Measurement. The conference will take place in hybrid format at the United Nations Headquarters in New York.

The Conference will bring together policymakers, practitioners, and experts from governments, civil society, international organizations, and academia to exchange experiences, good practices, and innovations in measuring corruption and the effectiveness of anti-corruption policies.

Through interactive plenaries, technical panels, and expert roundtables, the Conference will explore topics such as the operationalization of the Vienna Principles, the launch of the Global Anti-Corruption Digital Dashboard, and the metadata of the Statistical Framework to measure corruption. Sessions will also cover user-centred approaches, digital innovations, and emerging methods for collecting, analyzing, and using data to prevent and combat corruption.
