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.
