CorruptionRadar has developed a Sub-National Corruption Index (SCI). This index measures countries' and sub-national areas' grand and petty corruption levels based on 19 different dimensions measured with 807 household surveys. Users of the index will be able to separate corruption into petty and grand corruption for 178 countries and 1,483 subnational areas between 1995-2022.
