About the governance indicators
The Governance indicators contain the Subnational Corruption Database (SCD). SCD provides the levels of total (Subnational Corruption Index; SCI), grand, and petty corruption for 1,473 subnational regions within 178 countries. Grand perceptions and petty experiences are predominantly at the household level, sourced from 13 different organizations using 807 different surveys, in total. The data are available from 1995-2022. The SCI is available in two forms. The Baseline SCI only offers information in the years in which household surveys are available for a particular subnational area. These baseline data are most appropriate for (academic) research. The Comprehensive SCI uses methods of estimation, interpolation and extrapolation to arrive at a full series for each area. These comprehensive data are most appropriate for descriptive purposes or within-year comparisons.
