About

An open-access platform for locally measured corruption.

CorruptionRadar exists to make sub-national corruption legible - to researchers writing the next generation of governance studies, to journalists covering local accountability, and to policymakers whose interventions are sub-national whether the data is or not.

Mission

We provide comprehensive, up-to-date information on sub-national corruption - built on rigorous, peer-reviewed methodology and made freely available. We believe that shedding light on corruption at local levels is a prerequisite for the accountability that national-level statistics alone cannot deliver.

What we offer

The Subnational Corruption Index (SCI)

Our cornerstone is the Subnational Corruption Index, which measures grand and petty corruption across 1,473 regions in 178 countries, summarizing the experiences and perceptions of 1.3 million individuals across 807 household surveys. The methodology has been published in Nature Scientific Data.

Country profiles

Every country in the database has its own profile, with time-series charts, regional breakdowns, and downloadable per-country slices in CSV format. Profiles are generated directly from the published Baseline and Comprehensive datasets.

Methodology & documentation

The methodology page on this site walks through the index construction step by step - the source surveys, the harmonization, the imputation, and the validation - and links to the full data descriptor for those who want every detail.
